Apparatus consists of a close circuit through which water is circulated continuously by means of a centifugal pump of 25 mm x 25 mm couple to make the supply from sump tank.
A sump tank of 1200 mm x 500 mm x 1500 mm high fabricated with Electro plating Tank (PVC) is provided with the apparatus. A drain valve of 15 mm size is provided in the bottom of the tank.
A D.C.motor of 1 HP, single phase is privided with the apparatus. A variable speed drive and A.C. to D.C. convertor is also provided. A R.P.M. meter is also provided to measure revolution of the motor. Motor is attached with a swinging frame and spring balances to measure the output of the motor.
Discharge of water can be collected by the help of a collecting tank 400 mm X 400 mm X 400 mm fabricated with thick S.S.sheet. The tank is provided with gauge glass tube, flow divering arrangement and a drain valve of 25 mm size.
Complete G.I.piping system with foot valve, vaccum gauge and pressure gauge (located at suitable places) with necessary fittings are provided with the apparatus. A regulating valve is provided on the downstream side of the circuit to gulate the flow.
