The apparatus consists of a pipeline that contains one Bend meter. The pressure tapings from the Bend meter is taken to differential manometer to measure pressure difference. 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 valve are fitted in water line to conduct the experiment on different flow rates. Flow rate of water is measured with the help of measuring tank and stop watch.
