Hydraulic Ram (Closed Circuit)

The Hydraulic Ram is a pump which rise the water without any external power for its operation when large quantity of water is available at a small height, a small quantity of water can be raised to a greater height with the help of hydraulic ram. This works on the principle of water hammer.

It consists of a suitable size centrifugal pump 1 H.P. A Motor to make the supply from sump tank to supply tank. This apparatus consists of fiber coated MS sump tank of suitable capacity.
Supply tank : Fiber coated MS tank fixed on angle frame at a height of 20 meter.
Measuring tanks : Two fiber coated MS tank fitted with piezometric tube to measure the waste water and useful water. Air vessel is provided to perform the phenomena of water hammer. A pressure gauge is fitted on useful water pipe line to measure the head of water.

 To determine the following efficiency of hydraulic ram :
 Rankine’s efficiency
 D’Aubuisson’s efficiency
 To find the cavitation number of the flow.
