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.

This is a fluid machine question. Water reservoir is pumped over a hill through a pipe 450 mm in diameter and a pressure of 98.08 kPa is maintained in the summit water discharge is 30 m above the reservoir. The quantity pumped is 0.50 m3/s. rrictional losses in the discharge and suction pipe of the pump is equivalent to 1.5 m head loss. The speed of the pump is 800 rpm, what amount of energy must be furnished by the pump in kW?
The following system is fed by a centrifugal pump. The piping is constructed from smooth plastic of OD 55 mm, wall thickness 2.5 mm. The minor losses for the system prior to the pump are given by KL = 12.0. The system curves for this pump are attached. If the flowrate is reduced to 1.4 m3/hr, and the upstream head requirement were 17 m, what would the electrical power requirement of the pump be?
A water pump is used to pump the water to a large water tank as shown in Figure. The free surfaces of both water tanks are under atmospheric pressure. Dimensions and local losses are given below.
