The dam on Hydaway Lake on Liberty Mountain (not really sure if a dam exists) has the potential to provide some power to the Hydaway Outdoor Center. Before that can happen Sparky Consulting needs to determine the potential power output. A diagram of the dam and proposed turbine location are provided below. The lake water flows through an 8-inch diameter pipe (location A) into the turbine. The discharge pipe downstream of the dam has a volumetric flow rate of 300 ft3/min. The head loss through the piping system is 5 ft. The specific gravity of the water is 62.4 lbf/ft3. What is the power output (in horsepower) of the turbine if the turbine efficiency is 70 percent?
