Enter the average pump power output (watts) and the run time of the pump (min) into the calculator to determine the Pump Energy. 

Pump Energy Formula

The following equation is used to calculate the Pump Energy. 

Epump = AP * T*60

Variables:

  • Where Epump is the Pump Energy (Joules)
  • AP is the average pump power output (watts) 
  • T is the run time of the pump (min) 

To calculate the pump energy, multiply the average pump power by the run time of the pump in minutes, then multiply by 60.

How to Calculate Pump Energy?

The following two example problems outline the steps and information needed in order to calculate Pump Energy.

Example Problem #1:

  1. First, determine the average pump power output (watts). In this example, the average pump power output (watts) is measured to be 50.
  2. Next, determine the run time of pump (min). For this problem, the run time of pump (min) is calculated to be 40.
  3. Finally, calculate the Pump Energy using the formula above: 

Epump = AP * T*60

Inserting the values from above and solving the equation with the imputed values gives: 

Epump = 50 * 40*60 = 120,000 (Joules)

Example Problem #2: 

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as: 

average pump power output (watts) = 38

run time of pump (min) = 49

Entering these values into the formula or calculator above gives us: 

Epump = 38 *49*60 = 111720 (Joules)
