An oil pump is drawing 40 kW of electric power while pumping oil with p = 860 kg/m³ at a rate of 0.1 m³/s. The inlet and outlet diameters of the pipe are 8 cm and 12 cm, respectively. If the pressure rise of oil in the pump is measured to be 250kPa and the motor efficiency is 90 percent, determine the mechanical efficiency of the pump. 33.53 O 31.53 32.8 34.7 12 cm 14 Oil AP=250 kPa AP=2 0.1m³/s Pump 8 cm 40 kW کے Motor

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.
