Volumetric Efficiency of Gear Pumps Solution

STEP 0: Pre-Calculation Summary

Formula Used

Volumetric Efficiency of Pump = Actual Discharge of Pump for Gear Pump/Theoretical Discharge of Pump in Gear Pump*100
η_v = Q_ga/Q_gp*100
This formula uses 3 Variables

Variables Used

Volumetric Efficiency of Pump - Volumetric Efficiency of Pump is the ratio of actual discharge to the theoretical discharge.
Actual Discharge of Pump for Gear Pump - (Measured in Cubic Meter per Second) - Actual discharge of pump for Gear Pump is the actual amount of liquid pumped out in a minute.
Theoretical Discharge of Pump in Gear Pump - (Measured in Cubic Meter per Second) - Theoretical Discharge of Pump in Gear Pump is the volume of liquid pumped out in unit time.

STEP 1: Convert Input(s) to Base Unit

Actual Discharge of Pump for Gear Pump: 0.4284 Cubic Meter per Second --> 0.4284 Cubic Meter per Second No Conversion Required
Theoretical Discharge of Pump in Gear Pump: 0.843 Cubic Meter per Second --> 0.843 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_v = Q_ga/Q_gp*100 --> 0.4284/0.843*100

Evaluating ... ...

η_v = 50.8185053380783
