Abstract

Capacity of a pump is the fundamental data used in selecting certain pump. The flowing speed of the pump is very useful to determine the pumps capacity for irrigating process. This capacity must fulfill utilizing requirements which focus on two main criteria : 1) total capacity of pumps must provide maximum necessity (necessity on the highest point),  2) those pumps must be able to work efficiently and continously in the fluctuating condition. In order to fulfill the two criteria above it is necessary to use two ore more pumps with same capacity.
