EXPERIMENTAL STUDY THE PERFORMANCE OF RAM WATER PUMP

Ram water pump is one types of renewable energy that work without any source when used to provide energy from water power for changing the potential energy to kinetic energy to use for agriculture fields. The device must find near the rivers to useful from water to work and the waste water return to the river again. The performance of the ram pump is studied experimentally. The device is simple contain from fittings, tank, pipes, pressure vessel and valves. Three inlet diameter (1/2, 3/4 and 1 in) at inlet pipe is used, and three level of tank water supply (1.9, 1.8 and 1.65 m) is studied. Also, three ways is used to change the pressure in the vessel. The aim of this paper is studying the effect of change the inlet diameter and water level at the height and flow rate at the exit. Also, study the efficiency of the test device.

The results show inversely relationship between the head and flow rate at the exit and the pressure in the vessel is not effected to the head and exit flow rate. Additionally, the maximum efficiency is 29 % at 1.9 m tank height and 0.5 in diameter.
