A generator at a dam can supply 375 MW (375 x 10⁶ W) of electrical power. Suppose that the turbine and generator are 85% efficient.

1. Discover the rate at which falling water should supply energy to the turbine.

2. The energy of the water comes from a change in potential energy, U = mgh. What is the change in U required each second?

3. If the water falls 22 m, what is the mass of the water that should pass through the turbine each second to supply this power?
