The engineer is making an estimation for a home-owner. The owner has a small stream (Q = 1.4 cfs, T = 40°F) which is located at an elevation of H = 34 ft above the owner’s residence. The owner is proposing to dam the stream, diverting the flow via a pipe (penstock). This flow will spin a hydraulic turbine, that in turn will drive a generator to generate electrical power. Compute the maximum power in kilowatts which can be generated when there is no head loss and both the turbine and generator are of 100% efficient. Also, compute the power when the head loss is 5.5 ft, the turbine is 70% efficient, and the generator is of 90% efficient.
