Calculate Pump Efficiency







Formula

To calculate the Pump Efficiency:

\[ η = \frac{ρ \times g \times Q \times H}{P} \]

What is Pump Efficiency?

Pump efficiency is a measure of how effectively a pump converts the mechanical energy supplied to it (power input) into hydraulic energy (power output). It is calculated as the ratio of the power output to the power input, typically expressed as a percentage.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ η = \frac{1000 \times 9.81 \times 0.1 \times 10}{5000} = 0.1962 \text{ or } 19.62\% \]

The Pump Efficiency is 19.62%.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ η = \frac{850 \times 9.81 \times 0.05 \times 15}{3000} = 0.2081 \text{ or } 20.81\% \]

The Pump Efficiency is 20.81%.
