Friction losses in turbulent flow (Fanning Equation).pdf
This document discusses fluid flow in pipes, including laminar and turbulent flow regimes. It defines key terms like Reynolds number, friction factor, pressure drop, and boundary layers. For laminar flow, the friction factor can be predicted from the Reynolds number using theoretical equations. For turbulent flow, the friction factor must be determined experimentally and depends on both the Reynolds number and pipe roughness.
Basic Instrument Presentation ( Flow )
Flow is defined as the volume of material passing a specific place in a specified time interval. Common units of flow include gallons per minute, cubic feet per second, and tons per hour. Flow can be measured directly by measuring the volume passing over time, or indirectly by measuring changes in velocity, depth, or pressure and relating these to flow rate using primary and secondary measuring devices. Positive displacement meters and differential pressure meters are common types of flow measurement systems. Selection of a flow meter depends on factors like required accuracy, pressure loss, material properties, cost, and ease of installation and use.
Lecture 1.pptx

Piping Design_Unit 1.pptx
This document outlines the course details for a piping design course. It includes the instructor information, examination scheme, topics to be covered such as basics of fluid flow and head loss calculations, industries that require piping design, and codes and standards related to piping. Piping design is important for optimizing material flow within processing plants and avoiding disasters in heavy industries. Calculations of head loss involve considering both major losses due to friction and minor losses at fittings.
Unit41.pptx
Okay, let's solve this step-by-step:
* Given: Mass flow rate = 3 kg/s
* Inlet conditions: P1 = 1400 kPa, T1 = 200°C
* Exit conditions: P2 = 200 kPa
* Process is isentropic
* Properties of CO2 at given conditions: k = 1.3, R = 188 J/kg-K
* Using the continuity equation: ρ1A1V1 = ρ2A2V2
* Using the isentropic relations for ideal gases:
P1/P2 = (ρ2/ρ1)^k / (T2/T1)^(k-1)
Fluid Flow inside and outside of the pipe
- Internal flow is completely bounded by surfaces on all sides, such as pipe flows. External flow is over bodies immersed in a fluid that is unbounded, like flow over airfoils.
- Major losses in pipes are due to friction or viscous effects and are quantified using Darcy's friction factor. Minor losses are due to fittings.
- Laminar flow is smooth and orderly while turbulent flow is chaotic with eddies. The transition between them depends on the Reynolds number.
- In developing pipe flow, the boundary layer grows along the pipe until it fills the cross-section and the flow is fully developed.

The document discusses various principles and types of flow measurement devices. It covers:
- The three types of fluid flow: laminar, turbulent, and transitional as defined by the Reynolds number.
- Common differential pressure flow measurement devices like orifice plates and Venturi tubes, how they create pressure differences proportional to flow, and the equations used.
- Variable area flowmeters including rotameters which measure flow based on the height of a bob in the flow.

The document discusses various types of flow measurement. It begins by defining different types of fluid flow such as laminar, turbulent, and transitional flow. It then discusses primary flow elements like orifice plates and Venturi tubes that cause a pressure drop to measure flow. Orifice plates are simple but not very accurate while Venturi tubes are more expensive but more accurate. Other flow measurement techniques discussed include differential pressure meters, ultrasonic flow meters and the use of the Reynolds number to characterize flow regimes.
Lecture 2 flow phys6008
Here are the steps to solve this problem:
(a) Volume flow rate = πr^2v = π(0.1m)^2(2m/s) = 0.0314m^3/s
(b) Using the equation of continuity:
πr1^2v1 = πr2^2v2
(0.1m)^2(2m/s) = (0.03m)^2v2
v2 = 4m/s
So the velocity through the constriction is 4 m/s.

Design and optimization of ion propulsion drone
Electric propulsion technology is widely used in many kinds of vehicles in recent years, and aircrafts are no exception. Technically, UAVs are electrically propelled but tend to produce a significant amount of noise and vibrations. Ion propulsion technology for drones is a potential solution to this problem. Ion propulsion technology is proven to be feasible in the earth’s atmosphere. The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.
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.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
