DESCRIPTION :- The present Centrifugal Pump Test Rig is a self-contained unit operated on closed circuit basis containing a sump tank. The set-up consists of a Centrifugal pump coupled with an AC Motor. Flow of water is measured by using measuring tank and stopwatch. Vacuum gauge is fitted on suction line and Pressure gauge is fitted on delivery line to measure the pressure. EXPERIMENTATION :- ïƒ˜ To determine total head, overall efficiency and pump efficiency of the centrifugal pump. ïƒ˜ To plot Head vs Discharge, Pump efficiency vs Discharge, Pump HP vs Discharge.
