## How do you find theoretical displacement?

How to find displacement. In physics, you find displacement by calculating the distance between an object’s initial position and its final position. In physics terms, you often see displacement referred to as the variable s.

## What is the formula for pump?

Hydraulic Pump Formulas

Formula For: Word Formula: Letter Formula:
PUMP OUTLET FLOW in Gallons/Minute FLOW = RPM x PUMP DISPLACEMENT(Cu. In./Rev.) 231 Q = nd 231
PUMP INPUT POWER in Horsepower Required HORSEPOWER INPUT = FLOW RATE OUTPUT(GPM) x PRESSURE(PSIG) 1714 x EFFICIENCY(Overall) HP = QP or 1714 Eff GPM x PSIG 1714 Eff

What is the formula for calculating pump GPM?

The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM. (60 divided by 5 equals 12 gallons per minute.)

### How to calculate theoretical displacement of a pump?

There are two calculation methods for the theoretical displacement. One is to calculate geometrically the volume of the space enclosed by the teeth of the driving and driven gears. The other method first requires calculation of the theoretical torque of the pump.

### What is the operating pressure of a gerotor pump?
