Δ h = change in elevation (m, ft)
A body of 1000 kg is elevated 10 m . The change in potential energy can be calculated as
E p = (1000 kg) (9.81 m/s 2 ) (10 m)
= 98100 J
= 98 kJ
= 0.027 kWh
A body with weight (force) 500 lb f is elevated 30 ft . The change in potential energy can be calculated as
E p = ( 500 lb f ) (30 m)
= 15000 ft lb
A body with mass 15 slugs is elevated 30 ft . The change in potential energy can be calculated as
E p = ( 15 slugs ) ( 32.17405 ft/s 2 < ) (30 m)
= 14478 ft lb
You can estimate potential elevation energy (hydropower) in a tank or a reservoir by dividing the volume in horizontal slices and calculate the elevation energy for each slice - as it is done in the spreadsheet calculator below:
You can copy the spreadsheet to your Google Drive or to your local drive if you want to use it as a template for your own calculations.
