The turbines in a hydroelectric plant are fed by water falling from a 50m height. Assuming 91% efficiency for conversion of potential to electrical energy, and 8% loss of the resulting power in transmission, the mass flow rate of water required to power a 200 W light bulb needs to be calculated. Concept Introduction: Power can be calculated using energy as follows: Power = energy/time Here, energy can be taken as potential energy which is as follows: E P =mgh/time Thus, P = mgh Here, m is mass, g is acceleration due to gravity and h is height.
