venturi meter
Venturi meters use the Bernoulli principle and continuity equation to measure fluid flow rates. They consist of a converging section, throat, and diverging section. As the fluid flows through the converging section into the throat, its pressure decreases. This pressure difference is measured using a manometer and can be calibrated to determine flow rate, as flow rate is directly proportional to the square root of the pressure difference. Venturi meters are commonly used to measure flow rates of water, gases, and liquids in large diameter pipes.
venturi meter
This document discusses the working principle and components of a venturimeter, which is a device used to measure fluid flow rate based on Bernoulli's principle. The main parts of a venturimeter are the converging section, throat, and diverging section. As fluid flows through the converging section into the throat, where the cross-sectional area is smallest, its velocity increases and pressure decreases. The pressure difference between two points in the venturimeter, such as at the inlet and throat, can be measured with a manometer and used to calculate flow rate according to Bernoulli's equation. The actual discharge rate is slightly less than the theoretical value due to losses and is determined using a discharge coefficient.
Centrifugal pump
The document discusses centrifugal pumps. It describes how centrifugal pumps work by converting mechanical energy to hydraulic energy using centrifugal force. They work on the principle of forced vortex flow. Key components include an impeller that rotates and accelerates the fluid outward, and a casing that captures the fluid and converts its kinetic energy to pressure. Centrifugal pumps are used to pump liquids like water, sewage, petroleum and more. Performance curves are used to predict pump behavior under different operating conditions.
venturi_meter ppt(2)
Venturi meters use a restriction in a pipe to measure fluid flow rates. They have a converging section that narrows to a throat and then diverges again. This creates a pressure difference that can be used to calculate flow rate. Venturi meters have no moving parts, a small head loss, and do not easily clog. They work by applying Bernoulli's theorem between the inlet and throat, where the flow velocity increases and pressure decreases in the throat. Venturi meters can measure flow rates of various liquids and gases and are useful for high flow rates in large pipes, though they are large in size.

Flow measurement pdf
This document discusses different types of flow measurements. It describes four main types: 1) Primary or quantity meters that directly measure flow rate through volumetric or gravimetric methods. 2) Positive displacement meters that count discrete volumes of fluid flow. 3) Secondary or rate meters that infer flow rate from other measured properties like pressure or velocity. Common examples are Venturi meters, orifice plates, and rotameters. 4) Linear resistance element meters that rely on pressure drop across a tube to determine flow rate, suitable for very small, viscous flows. Primary meters are the most accurate while positive displacement meters can handle a variety of fluids. Secondary meters have varying accuracy depending on the design.
Flowmeter - Brief
This article provides a brief yet concise idea about flow meters and the pertinent terms related to them. This article classifies the different types of flowmeters and cites the different devices for measurement under these categories. Also, this article speaks about the major five classes of flowmeters viz. differential pressure, velocity, positive displacement, mass, and open channel.
Rotameter
Rotameter is a variable area flow meter that measures volumetric flow rate of fluids. It has a tapered glass or metal tube with a scale and a float inside. As fluid enters the bottom of the tapered tube, the float experiences upward buoyant force and downward gravitational force. It reaches equilibrium when the drag force equals weight-buoyancy force, indicating flow rate. Higher float position corresponds to greater flow rate due to larger flow area around the float. Pressure drop across the float depends on fluid density and flow area. Coefficient of discharge accounts for pressure losses to determine actual flow rate from measured float position.
Bernoulli's Principle and its applications
Daniel Bernoulli discovered Bernoulli's principle in the 18th century while studying water flow through containers. Bernoulli's principle states that as the velocity of a fluid increases, the pressure within the fluid decreases. Some applications of Bernoulli's principle include venturi tubes, perfume sprayers, pitot tubes, the curved path of spinning balls, and the lift force created by airplane wings. The presentation provided examples of how Bernoulli's principle explains these phenomena in fluids and discussed its importance.

The objectives are to study and compare the characteristics of venturi meters and orifice plates, calculate flow rates using measured pressure drops, and understand how rotameters operate based on the position of a float. An apparatus is described that can be used to collect pressure and flow rate data from each device to analyze flow measurement principles.
IRJET-Development of an Adjustable Cone Flow Meter and its Experimental Analysis
1. The document describes the development of an adjustable cone flow meter that aims to more accurately measure low fluid flow rates.
2. A traditional solid cone flow meter was designed, built, and tested experimentally. The results showed significant fluctuations in measurement accuracy at low flow rates due to small pressure drops that were difficult to measure.
3. To address this, an adjustable cone flow meter is proposed that can vary its "beta ratio" by adjusting the size of the flow restriction around the cone. A lower beta ratio at low flows would create a larger pressure drop for improved measurement accuracy. However, devising an internal adjustment mechanism presents engineering challenges.
Calibration of venturi and orifice meters
This experiment aims to calibrate venturi and orifice flow meters. The coefficient of discharge is obtained for both types of meters and plotted against Reynolds number. Pressure drop is also plotted against water flow rate. To calibrate the meters, a known volume of water is passed through and the flow rate is measured. The coefficient of discharge and Reynolds number are then calculated from the experimental data for both venturi and orifice meters.
unit-5-flowmeasurement.pdf
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.

wastewater Treatment for environmental chemistry.ppt
Wastewater treatment involves removing physical, chemical, and biological contaminants from wastewater through a multi-step process. The goal is to produce an environmentally-safe fluid and solid waste that can be disposed of safely. The treatment process typically involves preliminary screening and settling steps to remove large debris, followed by primary treatment to separate solids from liquids using sedimentation. Secondary treatment uses aerobic biological processes and flocculation to break down organic materials, and tertiary treatment may further polish the water using filtration or disinfection methods before environmental discharge or reuse. Proper wastewater treatment is necessary to protect water resources and public health.

Horizontal and vertical separators are discussed as well as factors considered in their sizing based on gas and liquid capacities.
Economics 151 Lecture 6-Market failures.ppt
This document discusses market failures that can occur when markets are not perfectly competitive. It identifies four main causes of market failure: externalities, public goods, imperfect market structures, and imperfect information. Externalities happen when third parties are impacted by transactions but are not included in pricing. Public goods are non-rival and non-excludable, making them difficult for private markets to provide efficiently. Imperfect information like asymmetric information or moral hazard can also lead to inefficient outcomes. The document uses examples and diagrams to illustrate how these market failures can result in resources being allocated inefficiently.
FUEL PYCARB that is pyrolysis and carbonization.pptx
This document compares pyrolysis and carbonization, two processes for thermally decomposing organic materials.

Key properties of SAW sensors are that they are passive, can be accessed wirelessly, have a wide operating range, rugged compact structure, high stability, sensitivity and low cost. The basic device consists of a piezoelectric substrate and input/output interdigitated transducers to launch and receive the waves. Emerging applications include automotive, medical and industrial
wastewatertreatment.ppt
Wastewater treatment involves removing contaminants from wastewater through three main stages: primary, secondary, and tertiary treatment. Primary treatment involves separating solids from wastewater via sedimentation. Secondary treatment uses bacteria and microorganisms to break down dissolved organic matter. Tertiary treatment disinfects the treated water through methods like chlorination or UV radiation before being discharged or reused. The sludge produced is further treated through aerobic digestion, anaerobic digestion, or composting before being disposed of or used as fertilizer.
FIXED BED FLUIDIZATION.pptx
Fixed bed fluidization can be classified as particulate or bubbling, depending on if it occurs in liquids or gases. As gas velocity increases through a solid particle bed, drag forces counteract gravity and cause the bed to expand. At a critical velocity, particles are uniformly suspended and minimum fluidization occurs. Industrial applications include fluidized bed reactors and dryers where heat and mass transfer are improved over fixed beds. Experiments showed relationships between pressure drop and velocity confirm theoretical equations in both gas and liquid fluidization.

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.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

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.

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.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

- 7. DIAGRAM
- 8. APPLICATION / USES Calculating the flow rate of fluid that is discharged in the pipe. Plumbing. Carburetor. The flow of chemical in pipelines. This is widely used in large-diameter pipes such as found in the waste treatment process. Also used in the medicine department for the measure, the flow rate of blood in arteries. This also used where high-pressure recovery is required.
- 9. ADVANTAGES Power loss is very less. This can be used where a small head is available. High reproducibility (the extent to which consistent results are obtained when an experiment is repeated). Accuracy is high over wide flow ranges. This can also be used for a compressible and incompressible fluid. This device is easy to operate. The coefficient of discharge (Cd ) for the venturi meter is high. This is widely used for high flow rate (Discharge).
- 10. DISADVANTAGES The installation cost of a venturi meter is high. There are little difficulties while maintenance. This device cannot be used where the pipe has a small diameter of 76.2 mm. Non-linear. This system occupies more space as compared to the orifice meter. It has a limitation of lower Reynolds number of 150,000. It is expensive and a little bulky.
