3. The manufacturers rating for a centrifugal pump shows that the pump delivers 160 gpm at 80 ft of head when the pump speed is 3000 rpm. This rating is for the best operating point of the pump: the efficiency at this point is 59 percent. (be careful with units) (a) Calculate the specific speed of the pump. (b) What is the horsepower required to operate the pump at the manufacturers rating? (c) A 1.8 horsepower motor with a speed...

You have been asked to design a similar pump from the
existing one. The existing pump works for water is of impeller
diameter equals 6 cm and its performance data is shown here when
working at 1725 rpm. The newly design pump is for a refrigerant
(R-134A) and it must produce 450 cm of head at 1600 rpm when
working at its best efficiency. One of your colleagues did
preliminary analysis and develop the performance curves in
dimensionless form for...

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...

(100 points) Water at 25°C is pumped at a rate of 0.075m'/s from a reservoir 20m above a pump to a free discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of 5in diameter cast iron. From the pump to the discharge the pipe is...
