A hydro-electric power station has a reservoir area of 2.7 km² and a capacity of 4.6 x 106 m³ . The effective head of water is 100 metres. The penstock, turbine and generation efficiencies are 95%, 90%, and 85%, respectively. Instructions :round off to 2 decimal places  1. Determine the total electrical energy that can be generated from the power station (kWh).  2. Determine the depth of the reservoir (metres)  3.Determine the fall in reservoir volume level is the load of 100 kW is supplied for 5 hours (%).

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 canhappen Sparky Consulting needs to determine the potential power output. A diagram of thedam and proposed turbine location are provided below. The lake water flows through an 8-inchdiameter pipe (location A) into the turbine. The discharge pipe downstream of the dam has avolumetric flow rate of 300 ft3/min. The head loss through the piping system is 5 ft. The specificgravity of the water is 62.4 lbf/ft3. What is the power output (in horsepower) of the turbine if theturbine efficiency is 70 percent?
