- Bernoulli's Principle states that the air pressure is lower where the air is moving faster, such as over the top of an airplane wing. This lower pressure provides lift, allowing planes and birds to fly. - The document uses diagrams and examples like a standing tennis ball to illustrate how Bernoulli's Principle works in practice by creating differences in air pressure. It explains that the faster moving air over the top of a wing results in lower pressure than under the wing, providing the upward lift necessary for flight.

The principle of bernoulli
The document discusses the principle of Bernoulli and provides examples of how it can be observed in everyday phenomena. It explains that Bernoulli's principle relates pressure and velocity in fluid flows such that an increase in velocity results in a decrease in pressure. Examples where this principle can be seen include water flows becoming narrower due to higher pressure on the edges, curved flight paths of spinning balls due to pressure differences, the danger of opening plane windows during flight from changes in pressure, boats bumping due to faster fluid flow between them, and birds being able to fly through higher air pressure under their wings compared to above.

Bernoulli’s principle
Daniel Bernoulli discovered Bernoulli's principle in the 1700s through experiments observing water flow. Bernoulli's principle states that as the speed of a fluid increases, the pressure decreases. It explains that the pressure is lowest where the flow speed is highest. Some applications of this principle are how aircraft wings generate lift through differences in air pressure above and below the wing, and how ventilation works through higher pressure pushing lower pressure areas.
Bernoulli’s principle
1) As the velocity of a fluid increases, the pressure of the fluid decreases.
2) Bernoulli's principle states that a region of fast-moving fluid has lower pressure than a region of slower-moving or stationary fluid.
3) Many common devices and phenomena rely on Bernoulli's principle, including aircraft wings, venturi tubes, and spray bottles.

Bernoulli's principle states that for an incompressible fluid flowing in a streamline manner, the sum of pressure, kinetic energy, and potential energy is constant at any point. It explains phenomena like lift in airplanes and boats. For airflow over an airplane wing, the faster-moving air over the top surface has lower pressure, creating an upward force. Bernoulli's principle also explains how drafts are formed when doors or windows are opened, allowing high-pressure hot air to rush out and low-pressure cool air to flow in. It governs the mechanics of sailing as well, with differential pressures creating lift on the sail to propel the boat forward.
Bernoulli's Principle
Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. The principle was introduced by Daniel Bernoulli in 1738 and describes the behavior of incompressible, non-viscous fluids. It explains various phenomena like aircraft lift, spoiler function, tennis ball motion, and carburetor/venturi tube operation. The document covers the theory, equation, and various applications of Bernoulli's principle.

Buoyancy & floatation
1) Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. This force is equal to the weight of the fluid displaced by the object and allows objects with lower density than the fluid to float.
2) The key factors that determine if an object will float or sink are the density of the object compared to the fluid density, the weight of fluid displaced versus the object's weight, and the object's shape.
3) Stability of floating objects depends on the location of the meta-center point, which is where the line of buoyancy force meets the axis when tilted. Stable equilibrium requires the meta-center to be above the center of gravity

1) Bernoulli's principle states that an increase in fluid velocity results in a decrease in pressure.
2) Pascal's law describes how pressure is transmitted equally in all directions throughout a confined fluid.
3) Continuity equations states that the flow rate of a fluid remains constant regardless of changes to its velocity or pressure.
4) Venturi tubes use the Bernoulli effect to create areas of lower pressure by increasing fluid velocity through constrictions.
Applications and Principle of bernoulli equation (Energy Conservation)
Short explanation about Bernoulli Principle and its vast areas of application in Automobile, day to day life etc. with various forms of energy equation.
Pressure
Pressure depends on the force applied over an area. It can be increased by either increasing the force or decreasing the area over which the force is applied. Pressure is calculated as force divided by area. Pressure acts equally in all directions within fluids as the particles collide with surfaces. Air pressure decreases with increasing elevation due to lower density, while water pressure increases greatly with depth.
Bernoulli Theorem
The document discusses Bernoulli's principle and its applications. It explains that Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. It provides examples of how Bernoulli's principle is applied in aviation to generate lift on airplane wings, and in venturi tubes where the constricted throat causes speed and pressure changes. It also discusses how Bernoulli's principle was applied in the design of traditional sloped rooftops to allow roofs to blow off safely during storms due to pressure differences.

Bernoullis equation
Bernoulli's principle states that an increase in the speed of a fluid results in a decrease in pressure. It is named after Daniel Bernoulli and can be expressed by the Bernoulli's equation: P + 1/2mv^2 + mgh = constant. Some applications of Bernoulli's principle include:
1) The lift of airplane wings, which occurs because the shape of the wings causes faster moving air over the top surface, resulting in lower pressure lifting the plane.
2) The curved path of a spinning baseball, which results from higher pressure on one side of the ball pushing it in that direction.
3) Atomizers use Bernoulli's principle to create a fine spray by drawing liquid up through a nozzle using
Refraction
This document discusses refraction and total internal reflection. It defines refractive index as the ratio of real depth to apparent depth. It provides examples of calculating apparent height when a glass block is placed over a stamp using the refractive index of glass. It also gives examples of calculating critical angle based on the refractive index and calculating angles of incidence and refraction when light passes between materials.
Applications of bernoulli principle
Bernoulli's principle states that as the speed of a fluid increases, the pressure within the fluid decreases. This principle explains how birds and airplanes can fly - the air moves faster over the top of the wing compared to the bottom, creating lower pressure above and higher pressure below, resulting in an upward lift force. It also describes how spoilers on racecars work to provide better traction by creating downward force. Bernoulli's principle is applied in many everyday examples like wind over roofs, curveballs, golf ball dimples, shower curtains, and atomizers.

Archimedes principle
Archimedes' principle states that the buoyant force on an object submerged or partially submerged in a fluid is equal to the weight of the fluid the object displaces. This principle can be used to calculate density and relative density. It also explains why ships and submarines float or sink depending on whether the object's density is greater than, equal to, or less than the fluid it is placed in. Applications of Archimedes' principle include ship building, submarine operations, and how certain aquatic animals and balloons are able to achieve buoyancy.
Hydrostatic pressure
This document provides an overview and instruction on hydrostatic pressure for students, including defining hydrostatic pressure, discussing pressure measurement devices like manometers, calculating pressure at various points, and providing examples of solving hydrostatic pressure problems. The goal is for students to understand how pressure varies with depth in fluids, be able to use equations to calculate pressure, and describe common pressure measurement tools including piezometers, U-tube manometers, and inclined tube manometers. Practice problems are provided to help students apply the concepts.
Archimedes principle
Archimedes' principle states that when an object is fully or partially submerged in a fluid, it experiences an upthrust equal to the weight of the fluid displaced. This principle explains why objects float or sink based on their density. If an object's density is greater than the fluid, it will sink, and if its density is less than the fluid, it will float. The upthrust force reduces the apparent weight of the submerged object. Applications of Archimedes' principle include determining ship drafts, submarine depths, and fluid densities using instruments like hydrometers.
Buoyancy.ppt
Buoyancy and pressure in fluids are discussed. Objects experience an upward buoyant force when submerged in fluids due to higher pressure at deeper levels pushing up on the bottom of the object. Archimedes' principle states that the buoyant force equals the weight of fluid displaced by the object. The buoyant force can be calculated by subtracting the weight of the object in water from its weight in air.
Bernoulli's principle
1. Bernoulli's principle states that within a horizontal flow of fluid, the highest fluid pressure occurs where the flow speed is lowest, and lowest pressure where flow speed is highest.
2. Bernoulli's principle explains how the difference in pressure above and below a wing produces an upward force, allowing for flight. It is also applied to explain how air flows over mountains.
3. Bernoulli's equation expresses the conservation of energy for flowing fluids, relating pressure, flow velocity, and elevation. It states that the total mechanical energy per unit volume remains constant within a streamline.
Bernoulli theorm
This document describes an experiment to verify Bernoulli's theorem. Bernoulli's theorem states that for an inviscid, incompressible fluid flowing steadily through a closed passage, the total energy at any point remains constant. The experiment involves measuring the pressure, velocity, and elevation at different points in a diverging duct carrying water. Observations are recorded and used to plot the total energy line, which should be horizontal according to Bernoulli's theorem. The results support the theorem by showing the total energy remains constant despite changes in pressure, velocity, and elevation along the duct.
Lift principles
In this presentation, we discussed the different principles explaining the lift generation. Principles such as venturi's principle and time-lapse theory became invalid. The correct theory for the lift generation is explained in this ppt.
AEROPLANES CREATING LIFT BY GIRISH HARMUKH

Factors affecting lift such as airspeed, density and wing shape are also covered.

Wing design project
Daniel Bernoulli was a Swiss scientist who discovered the Bernoulli Principle, which describes conservation of energy in fluid mechanics. The principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases. This principle is important for flight, as it explains how the differences in air pressure above and below a wing create lift. Bernoulli's work led to technologies that enabled the development of motor vehicles and airplanes.
GEOG100--Lecture 06--Atmospheric and ocean circulation
The document summarizes key concepts about atmospheric and oceanic circulation. It discusses how air pressure, temperature, and density are related, and how changes in one can impact the others. It explains the three main forces that influence wind patterns - the pressure gradient force, Coriolis force, and friction. The interaction of these forces determines global wind circulation and ocean currents. Specific circulation patterns discussed include the Hadley cell, jet streams, monsoons, and the ocean's thermohaline circulation.
Bernoulli's principle
Team A7 “Aerial Ace” uses Bernoulli's principle and equations to explain how airfoils generate lift for flight. Bernoulli's principle states that as the speed of a fluid increases, the pressure decreases. According to the continuity equation, the asymmetric shape of an airfoil causes the air flowing over the top surface to increase in velocity compared to the air on the bottom surface. This increase in speed leads to a decrease in pressure on top of the airfoil, while the pressure remains higher below the airfoil. The difference in pressure generates lift, allowing the airfoil and airplane to become airborne.
Forces acting in an airplane edwin pitty s.
The four main forces acting on an airplane in flight are thrust, drag, lift, and weight. Thrust is produced by the engine and propeller and opposes drag. Drag is a retarding force caused by air flowing around the airplane. Weight pulls the airplane downward due to gravity, and lift opposes weight and is produced by air flowing over the wings. Understanding and controlling these four forces through power and flight controls is essential to flight.

The Pressure is On!
Atmospheric pressure is caused by the weight of air molecules pushing down on surfaces. Experiments with syringes and bottles show that compressed air pushes back with an equal and opposite force called pressure. When air is pushed into a smaller space, the molecules move closer together, resulting in compressed air. Atmospheric pressure pushes in all directions and is responsible for the movement of air through convection currents, which influence Earth's climate.

A review on techniques and modelling methodologies used for checking electrom...
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
