An engineer is making an estimate for a home owner. This owner has a small stream of water (Q=1.4cfs T=40C)that is located at an elevation H=34ft above the owner's residence. The owner is proposing to dam the stream, diverting the flow through a pipe. This flow will spin a hydraulic turbine, which in turn will drive a generator to produce electrical power, Estimate the maximum power in kilowatts that can be generated if there is no head loss and both the turbine and generated are 100% efficient. Also estimate the power if the head loss is 5.5 f, the turbine is 70% efficient, and the generator is 90% efficient. Do you think the home owner should go ahead with is idea?
