Abstract
When an existing pumping system will be used as a component of an irrigation system, it is necessary to measure the capacity of the pump so that the irrigation system can be designed to operate efficiently using the available flow rate and pressure. This requires measuring pump discharge rates and pressures at several points over the available range. Flow meters or volumetric methods can be used to measure discharge rates, while pressures are easily measured with pressure gauges. This document presents procedures for measuring pump capacity and also this work discusses factors affecting pump capacities under field conditions.
