Here is how the Pump Slippage equation looks like.

0.4146 = 0.843 - 0.4284

0.4146m³/s = 0.843m³/s - 0.4284m³/s

0.4146 = 0.843 - 0.4284

Pump Slippage Solution

Follow our step by step solution on how to calculate Pump Slippage?

FIRST Step Consider the formula

S = Q gp - Q ga

Next Step Substitute values of Variables

∴

S = 0.843m³/s - 0.4284m³/s

Next Step Prepare to Evaluate

∴

S = 0.843 - 0.4284

LAST Step Evaluate

∴

S = 0.4146m³/s
