Assume that the pipe size from the tank to the centrifugal pump is reduced to 0.5 inch.
How would it affect the suction side pressure and operation of the pump?
Just need help with the theory. I believe I need Bernoulli's equation.
Homework Answers
By Bernoulli theorem,
P + 1/2 * rho*v2 + rho*g*z = constant
If we this theorem applying into the centrifugal pump and tank then
If we reduced pipe size to 0.5 inch then by continuity equation velocity of pipe increases and when velocity increasing then by Bernoulli theorem suction pressure reduces. Elevation pressure in both case is same
P1 + 1/2 * rho*v12 = P2 + 1/2 * rho*v22
Diameter reduced upto 0.5 inch
Then v2>v1
Then P2<P1
Suction pressure reduced.

A centrifugal pump is used to pump water at 77ºF from a reservoir whose surface is 20 ft above the centerline of the pump inlet. The Pipe System consists of 67.5 ft of PVC pipe with a 1.2 in ID and negligible average internal roughness height. The length of the pipe from the bottom of the lower tank to the pump inlet is 12 ft. There are several minor losses in the pipe: an acute edge entry (KL = 0.5),...
