Water is pumped from a deep well (located 20 m underground) to a hilltop reservoir (located at 50 m above ground level). Water is being transferred at a rate of 4800 LPM while the pump consumes 60,000 kW of electric power in the process. Assume that there are no frictional losses in the piping system and the change in kinetic energy between the inlet and outlet of the piping system is negligible. Determine the overall efficiency of the pump-motor setup.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Water is to be pump from a reservoir with a temperature of 32°C at sea level. Friction loss at suction is 0.3m and the suction elevation is 2.45m below pump centerline. Determine the available NPSH for this pump installation if at 32°C, Psat=4.798kPa & specific volume is 0.001006m^3/kg.
The demand for electric power is usually much higher during the day than it is at night, and utility companies often sell power at night at much lower prices to encourage consumers to use the available power generation capacity and to avoid building new expensive power plants that will be used only a short time during peak periods. Utilities are also willing to purchase power produced during the day from private parties at a high price. Reservoir 50 m Pump- turbine Lake 7- Suppose a utility company is selling electric power for $0.06/kWh at night and is willing to pay $0.13/kWh for power produced during the day.
