| Abstract | ||||
| One of the costiest items in agriculture is the cost of providing water. The purpose of this investigation is to operate the turbine pumps to cope with the irrigation water and pressure requirements for the existing system of irrigation. It is also desired to maintain a constant pump discharge for different static water levels by varying the pump speed to adjust an increase or decrease in water discharge. The study was carried out on two turbine pumps at the College Research Station, each of which has fourteen stages; these pumps are supposed to irrigate the College Farm including two centre pivots. The system head curves were constructed, points of intersection with the pump characteristic curves at different pump speeds, are the operating points, which could be used to give the required discharge and pressure at a specified pump speed according to the given tables for the gross irrigation water requirements. Equations of system head curves and pump characteristic curves are presented, from which the operating points could be obtained. | ||||
