Abstract
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.

The design and performance evaluation of a downdraft hydraulic ram pump when the results showed at 2-in diameter the minimum inflow 2.4 gal/min and discharge 0.2 gal/min
Summary
A pump is a device that used to move and transfer the fluids from point to another by mechanical action. Many uses of pumps that operated at the energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications to large industrial pumps [1] Many studies in this area to study the ram water pump. The effect of diameter and length of drive pipe, flow rate at exit, pressure at waste valve and the power of hydro ram was studied [6]. The hydraulic ram is sometimes used in remote areas, where there is both a source of lowhead hydropower, and a need for pumping water to a destination higher in elevation than the source In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water [7]. All the components of the test rig are design based on the manual of hydraulic ram pump [9] that tabulated and description in Fig. 3 and Table 1
