The formula to calculate the Pump Energy (Epump) is:
\[ \text{Epump} = \text{AP} \times \text{T} \times 60 \]
Where:
Let's say the average pump power output (AP) is 500 watts and the run time of the pump (T) is 10 minutes. Using the formula:
\[ \text{Epump} = 500 \times 10 \times 60 = 300000 \text{ Joules} \]
So, the pump energy is 300,000 Joules.
