A centrifugal pump is used to lift water from a water reservoir with level 1 m below the pump center line. Then, to another reservoir with level 7 m above the center line. Pressure gages readings from the suction and discharge are 1 bar and4 bars respectively. The flow rate at 1.27 m /s with pipe inside diameters of 400 mm at suction and 250 mm at the discharge. Assume over all head loss due to frictibn of 4 J/N, if the pump has an efficiency of 80% what is the brake power in kW?

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.
