|On the static suction head of a pump|
Energy conditions in a suction system are discussed with respect to the cavitation properties of a pump. A general instruction for the static suction head evaluation is described. The static suction head determines the insta/lation of a pump in terms of its height above the lower reservoir level. The evaluation is demonstrated on three practical examples.
