Solved If you want to store 2.0 mJ of energy in a 10-μF
If you want to store 2.0 mJ of energy in a 10-μF capacitor, how much potential do you need to put across it? There are 2 steps to solve this one. You need to use the formula for the potential energy stored in a capacitor, which is E = 0.5 × C × V 2.
Energy to pressurize.
When Head 2 = 2 * Head 1, then Power pump 2 = 2 x Power pump 1. It seems simple to see now that, if both pumps run for time T, P * T = Energy, so pump 2, pressurizing at 2 x Head 1, consumes 2 x Power over the same time T to fill each vessel, so Energy used by pump 2 is 2 * Energy consumed by pump 1.
