Homework Answers
Centrifugal pump uses impellar to move water from one point to another.
P1 is the suction pressure and P2 is the discharge pressure.
If the flow rate increases, both the pressures will increase.
Also the differential pressure (P2-P1) will decrease, meaning the difference between both will decrease with increased pressure.

Chemical Engineering Fluid Mechanics 30. The purpose of a centrifugal pump is to increase the pressure of a liquid in order to move it through a piping system. The pump is driven by a motor, which must provide sufficient power to operate the pump at the desired conditions. You wish to find the pressure developed by a pump operating at a flow rate of 300 gpm with an oil having a specific gravity (SG) of 0.8 and a viscosity of...
