" Pedal Powered Water Purification By Reverse Osmosis"
The Earth is covered in over 75% water, yet one of the world’s greatest issues is a lack drinking water. “Nearly one billion people do not have access to clean drinking water”. That is about one eighth of all the people living on earth right now. Every year, almost four million people die from water-related diseases and 98% of those occur in the developing world. Humans can live for weeks without food, but only a few days without water. Many people in developing countries barely have access to any water source at all and for those that do, the water is completely filthy and disease-ridden.
Clearly, access to potable water around the world is an exceedingly urgent issue in which action should be taken immediately. In response to such a need, this idea is proposed to produce clean drinking water by reverse osmosis filtration by means of human power. There are several means to purify water; however, because of its incredible thoroughness, a reverse osmosis system has been preferentially selected for this design
Pendulum operated water pump
The document describes a pendulum-operated piston pump designed to alleviate the work required to pump water. The pump uses the oscillating motion of a pendulum connected to a two-armed lever to power the up-and-down motion of a piston inside a cylinder. With each swing of the pendulum, the lever moves the piston to pump water with minimal human effort. The pendulum's motion can be maintained by occasional finger movements, requiring less fatigue than traditional hand pumps. The device aims to create free energy through the difference between the work of oscillating forces on the lever and damping forces on the pendulum.

2) Reciprocating pumps use a piston or plunger that executes a reciprocating motion inside a closed cylinder to push the fluid, with common examples including piston pumps and diaphragm pumps.
3) Diaphragm pumps use a flexible diaphragm and check valves to pump fluids, and can handle corrosive or abrasive liquids since the only parts in contact with the fluid are the valves.

Centrifugal pump
The centrifugal pump consists of an impeller that rotates within a casing and uses centrifugal force to convert mechanical energy into hydraulic energy or pressure energy. As fluid enters the center of the impeller, the rotating vanes accelerate the fluid and discharge it outward into the casing. The casing, typically a volute, then converts the fluid's kinetic energy into increased pressure, causing the fluid to exit the pump at a higher pressure than when it entered. Proper pump operation relies on balancing factors such as suction head, delivery head, and mechanical efficiency to move fluid while avoiding cavitation that can damage pump components.

1. A pump transfers liquid from one place to another by using mechanical energy to impart rotational or reciprocating motion. The document discusses different types of pumps including reciprocating pumps, rotary pumps, centrifugal pumps, and their basic components and operating principles.
2. Centrifugal pumps work by using an impeller to impart centrifugal force on the liquid, increasing pressure and transferring it outward through a volute casing. Key components include the impeller, casing, wear rings, and shaft/sleeve assembly.
3. Reciprocating pumps use pistons or plungers and check valves to trap and displace fixed volumes of liquid on each stroke, pushing it to a higher pressure discharge point.
Pumps
A pump is a mechanical device that transfers rotational energy to liquid to move it from one place to another. There are two main types of pumps: dynamic and positive displacement. A reciprocating pump is a type of positive displacement pump that uses a piston or plunger to trap and move liquid. A rotary pump also positively displaces liquid but does so continuously rather than reciprocating. A centrifugal pump is a type of dynamic pump that uses a rotating impeller to accelerate liquid and convert kinetic energy to pressure energy to move the liquid.
Fpe oep
A centrifugal pump works by using a rotating impeller to impart centrifugal force on water and push it outward, increasing its velocity and pressure. As the water is pushed through and restricted by the pump casing, pressure builds up. There are two main components - stationary parts like the casing and bearings, and rotating parts like the impeller and shaft. Centrifugal pumps are simple to construct, can handle liquids with solids, have low maintenance costs, but are not as efficient for viscous liquids or at high heads.
Centrifugal pump
This document discusses centrifugal pumps. It begins by defining pumps and their purpose of increasing fluid velocity, pressure, or elevation. It then classifies centrifugal pumps and describes their operation of converting motor energy into kinetic and potential energy of fluid flow using a rotating impeller. The key parts of centrifugal pumps are identified as the impeller, casing, suction pump, and discharge pump. The working principle is explained as fluid being accelerated outward by centrifugal force when the impeller rotates. Centrifugal pumps are commonly used for water supply, industry, and domestic applications due to their simplicity, low cost, and efficiency.
Pump
A pump is a mechanical device that uses mechanical energy to move fluids or convert mechanical energy to hydraulic energy. It is commonly used to elevate fluids, pressurize fluids, or impart kinetic energy to fluids.
A centrifugal pump has several key components, the most important being the impeller. The impeller rotates to impart centrifugal force and push liquid outwards. Impellers can be open, semi-closed, or closed depending on the type of liquid being pumped.
Centrifugal pumps can be arranged either horizontally or vertically depending on space limitations, drive arrangements, and other requirements. Vertical pumps are now more commonly used due to better efficiency and space considerations compared to horizontal pumps.
Classification of centrifugal pump pwi
This document classifies and describes different types of centrifugal pumps. It discusses closed and open impellers based on whether vanes are enclosed or exposed. It also describes volute, diffuser, and vortex pumps based on their casing design. Volute pumps gradually increase area to reduce velocity and increase pressure. Diffuser pumps use fixed vanes to gradually convert velocity to pressure. Vortex pumps add a circular chamber between the impeller and volute to further convert kinetic to pressure energy.

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.
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
