Discharge Over Notches Apparatus - Elabengineering

The Lab setup consists of a channel having sufficient length and width in which water is supplied from the bottom. Required Notch is fitted at one end of this channel .A hook gauge with Vernier scale is fitted to measure the height of fluid in flow channel. Arrangement for fixing interchangeable notches is made. Set of three brass notches, i.e. rectangular notch. 60 V notch & 45 V notch provided along with the set up. Present set – up is self –contained water re- circulating unit .provided with a sump tank and a centrifugal pump etc. Flow control valve and by-pass value are fitted in water line to conduct the experiment on different flow rate .Flow rate of water is measured with the help of measuring tank and stopwatch.
