Estimate the potential energy stored in a volume - like a tank or any kind of reservoir - by
5
dividing the volume of the tank or reservoir in horizontal slizes
6
calculate the potential energy in each slice
7
summarize the potential energy for all slizes
8
9
Use the table below as a template:
10
divide your volume in horizontal slices
11
estimate and add the area and height of each slice
12
estimate and add the middle elevation of each slice above the pump or turbine
13
adjust the other parameters if required
14
potential energy for each slice and summarized energy are calculated
