This set-up consists of 2 pipes of different diameters, which are connected in parallel. Pressure tapings are provided on each pipe to measure the pressure losses with the help of a Differential Manometer. Control valves are fitted on each pipe, which enables to use one pipe at a time for experiment. Present set-up is self-contained water re-circulating unit, provided with a sump tank and a centrifuge pump etc. Flow control valve and by-pass valve are fined 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.
