An engineer is making an estimate for a home owner. This owner has a small stream (Q = 0.05 m³/s) that is located at an elevation H = 11.6 m above the owner's residence. The owner is proposing to dam the stream, diverting the flow through a pipe (penstock). 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 generator are 100% efficient. Also, estimate the power if the head loss is 1.9 m, the turbine is 75% efficient, and the generator is 94% efficient. -Penstock Turbine and generator

An engineer is making an estimate for a home owner. This owner has a small stream (Q =
0.05 m³/s) that is located at an elevation H = 11.6 m above the owner's residence. The
owner is proposing to dam the stream, diverting the flow through a pipe (penstock). 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 generator are 100% efficient. Also, estimate the power if the
head loss is 1.9 m, the turbine is 75% efficient, and the generator is 94% efficient.
