Pump Slippage Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pump Slippage = Theoretical Discharge of Pump in Gear Pump-Actual Discharge of Pump for Gear Pump
S = Q_gp-Q_ga
This formula uses 3 Variables

Variables Used

Pump Slippage - (Measured in Cubic Meter per Second) - Pump slippage is the difference between the theoretical discharge and the actual discharge.
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.
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.

STEP 1: Convert Input(s) to Base Unit

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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = Q_gp-Q_ga --> 0.843-0.4284

Evaluating ... ...

S = 0.4146

STEP 3: Convert Result to Output's Unit

0.4146 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.4146 Cubic Meter per Second <-- Pump Slippage

Theoretical Discharge given Outer and Inner Gear Diameter

Go Theoretical Discharge of Pump in Gear Pump = pi/4*(Outer Diameter of Gear Teeth^2-Inner Diameter of Gear Teeth^2)*Angular Speed of Driving Member in Gear Pump

Width of Rotor given Volumetric Displacement

Go Width of Rotor = (4*Theoretical Volumetric Displacement in Gear Pump)/(pi*(Outer Diameter of Gear Teeth^2-Inner Diameter of Gear Teeth^2))

Theoretical Volumetric Displacement of External Gear Pump

Go Theoretical Volumetric Displacement in Gear Pump = pi/4*Width of Rotor*(Outer Diameter of Gear Teeth^2-Inner Diameter of Gear Teeth^2)

Pump Slippage Percentage

Go Pump Slippage Percentage = ((Theoretical Discharge of Pump in Gear Pump-Actual Discharge of Pump for Gear Pump)/Theoretical Discharge of Pump in Gear Pump)*100

Angular Speed given Theoretical Discharge and Volumetric Displacement

Go Angular Speed of Driving Member in Gear Pump = Theoretical Discharge of Pump in Gear Pump/Theoretical Volumetric Displacement in Gear Pump

Theoretical Discharge of External Gear Pump

Go Theoretical Discharge of Pump in Gear Pump = Theoretical Volumetric Displacement in Gear Pump*Angular Speed of Driving Member in Gear Pump

Volumetric Efficiency of Gear Pumps

Go Volumetric Efficiency of Pump = Actual Discharge of Pump for Gear Pump/Theoretical Discharge of Pump in Gear Pump*100

Actual Discharge given Volumetric Efficiency and Theoretical Discharge

Go Actual Discharge of Pump for Gear Pump = (Volumetric Efficiency of Pump*Theoretical Discharge of Pump in Gear Pump)

Theoretical Discharge given Volumetric Efficiency and Actual Discharge

Go Theoretical Discharge of Pump in Gear Pump = Actual Discharge of Pump for Gear Pump/Volumetric Efficiency of Pump

Theoretical Discharge given Pump Slippage

Go Theoretical Discharge of Pump in Gear Pump = Pump Slippage+Actual Discharge of Pump for Gear Pump

Actual Discharge given Pump Slippage

Go Actual Discharge of Pump for Gear Pump = Theoretical Discharge of Pump in Gear Pump-Pump Slippage

Pump Slippage

Go Pump Slippage = Theoretical Discharge of Pump in Gear Pump-Actual Discharge of Pump for Gear Pump

Pump Slippage Formula

Pump Slippage = Theoretical Discharge of Pump in Gear Pump-Actual Discharge of Pump for Gear Pump
S = Q_gp-Q_ga

What is discharge of a pump?

Discharge of a pump is defined as the amount of a liquid pumped out in unit time. It is also called as flow capacity of a pump.

How to Calculate Pump Slippage?

Pump Slippage calculator uses Pump Slippage = Theoretical Discharge of Pump in Gear Pump-Actual Discharge of Pump for Gear Pump to calculate the Pump Slippage, Pump Slippage refers to the difference between a pump's actual flow rate or discharge and its theoretical or ideal flow rate. It occurs due to various factors such as internal leakage, fluid recirculation within the pump, and slip between the impeller and the fluid being pumped. Pump Slippage is denoted by S symbol.

How to calculate Pump Slippage using this online calculator? To use this online calculator for Pump Slippage, enter Theoretical Discharge of Pump in Gear Pump (Q_gp) & Actual Discharge of Pump for Gear Pump (Q_ga) and hit the calculate button. Here is how the Pump Slippage calculation can be explained with given input values -> 0.4116 = 0.843-0.4284.
