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.

Question

06(a). A centrifugal pump lifts water from a sump to an overhead reservoir. The static lift is 40 m out
of which 3 m is suction lift. The suction and delivery pipes are both of 30 cm diameter. The friction
loss in suction pipe is 2.5 m and in delivery pipe it is 7.5 m. The impeller is 0.5 m in diameter and has a
width of 3 cm at the outlet. The speed of the pump is 1200 rpm. The exit blade angle is 20°. If the
manometric efficiency is 86%, determine the absolute pressures at the suction and delivery ends of
the pump. Assume that the inlet and outlet of the pump are at the same elevation. Take atmospheric
pressure as 10.10 m of water.
