The owners of a house on a private lake are thinking of using "pumped storage" as a means of reducing their electricity bills. They will pump water from the lake up to a large reservoir overnight, and then during times of peak power prices, release the water to run back down to the lake, through a turbine, generating power for the house. In this case, the large reservoir (a big pond) is located 8 m (vertical) above the water level of the lake. The piping used to pump water into the reservoir is 20 cm in diameter; the pump is at the same level as the lake. The  homeowners plan to restrict the flowrate to 0.2 m3/s. What is the minimum power required for the pump in this case?
