Question:

Water is flowing in a river at 2.5 m/s. The river is 40 m wide with an average depth of 6.0 m. Compute the power available from the water current.

Energy Conservation:

In a closed system, the total energy is conserved. That means the sum of the kinetic energy and the potential energy of the system (mechanical energy) doesn't change during the course of events. When heat, sound or friction are involved, the energy conservation should consider those effects.
