Fluid dynamics

A 30-inch diameter steel pipe (ɛ = 0.00020 feet) delivers water from a reservoir into a hydroelectric turbine
and then empties into a river. The flow in the pipe is 100 cfs. The length of the pipe is 750 feet. The water
surface elevation in the reservoir is 300 feet above the water surface elevation in the river. The efficiency
of the turbine is 90%. Use the Darcy-Wiesbach equation to determine the friction head loss. Assume minor
losses are 20% of the friction head loss. The water temperature is 40°F. Determine the power generated
by the turbine in horsepower (hp) and in kilowatts (kW).
