Changing the potential energy of water is frequently used as a means of storing excess renewable energy when it is not needed and using it when it is needed. An electrically-powered pump with efficiency 62 % raises a 10 kg mass of water a height of 10 m. The water is subsequently allowed to return to its original elevation while passing through an electricity-generating device with efficiency 84 %. Calculate the percentage of the electricity originally used to pump the water that is recovered by the entire process.
I haven't a clue where to begin, this is energy systems engineering. Would you derive an equation for the electric pump and then the electricity generator? In need of serious guidance
