A double-acting reciprocating piston pump which has a stroke length of 350 mm and a bore of 175 mm, takes water in from a sump 3 m below and delivers it at a height of 46 m above the pump level. Both the suction and delivery pipes have a diameter of 100 mm and lengths of 6 m and 75 m respectively. The pump piston follows the motion of a simple harmonic at 40 double strokes per minute. Large air vessels are fitted on both sides of the pump. On the suction side is the air vessel 1.5 m and on the delivery side 4.5 m away from the pump. The Darcy's coefficient of friction for both pipes is 0.008. Calculate the pressure difference across the piston at the beginning of the stroke.

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.
