This document describes a measurement project to determine flow rates using different shaped and angled weirs and notches. The project uses a basic model of a tank and pipes to release water samples through notches of varying shapes. Flow rates are then measured and compared for different notch configurations. The goal is to understand how notch shape impacts flow rate, which has applications in estimating floods and controlling water distribution for various purposes. Flow measurements will be taken for water released through notches over set periods of time.
Weir notches
- 2. FLOW : Liquid, gas, or electricity move steadily and continuously in a current or stream. FLOW RATE : The volume of fluid which passes per unit time; usually represented by the symbol Q (sometimes V̇ ). The SI unit is m3/s (cubic metres per second). WEIR &NOTCH : The purpose of weir & notch is to measure discharge of fluid specially water . Notch is smaller one made of iron plate, steel , tin etc specially used in hydraulics laboratory for students to measure the discharge of water or flow .Weir is the bigger one found in field across a water course, nullah , small river etc made of stone or concrete This main aim of this project is to measure flow rate for different shaped notches and different angled notches.
- 3. The project is based on measuring flow rate for different shaped notches and weirs. We use a tank and pipes to construct the basic project model. We use this basic model for measuring flow rate of a water sample. This project has many uses and further in future the knowledge about notches and weir is vey important.
- 4. 1.Weir structure 2.Notch structure We can measure at what rate Water is released which is used to guess floods. We can expel only required amount of water and we calculate the amount of water required for different purposes It has a greater significance in various scientific fields
- 5. This is an experiment which is used for the measurement of flow rate of water using Notches . The flow rate of water will be different for different shaped notches. We construct a tank and two pipes to it and at the end of each pipe we arrange a plastic piece which acts as notch We fill the tank with water and release them through pipes We collect the water at the end of pipes and we find the amount of water collected using the formulae After that we find amount of water flowed out for a certain time i.e., flow rate and we compare the values for different shaped notches We compare the values for different shaped notches
- 6. :
- 9. The amount of water discharged for a particular time i.e., Rate of flow for different shaped notches are different . BATCH-19 SECTION-35 BY:- 160070396 160070398 160070399 160070403 160070404
