Steam Pump Capacity

The flow to the discharge system is termed the pump capacity. The capacity, usually expressed in U.S. gallons per minute (cubic meters per minute), is somewhat less than the

theoretical displacement of the pump. The difference between displacement and capacity is called slip. The displacement is a function of the area of the liquid piston and the speed at which the piston is moving.

The displacement of a single double-acting piston can be calculated from the formula
