A centrifugal pump having four stages in parallel, delivers 12 kiloliters per minute of liquid against a head of 25m. The diameter of the impeller being 24cm and a speed of 1800rpm. A pump is to be made up with a number of stages in series. In similar construction to that of the first pump to run at 1250rpm and to deliver 15 kiloliter/min against a total head of 250m. Find the diameter of the impellers and the number of stages required in this case. The most common condition is that of pumping water from a sump, as illustrated diagrammatically in figure below. Data: Water temperature 90°F., sea level, friction and turbulence loss in the suction line 1 ft., suction lift 8 ft. What is the available suction head? The vapor pressure corresponding to 90°F is 0.698lb. per sq. in. abs. and the specific gravity is 0.997. per sq. in. abs. and the specific gravity is 0.996.

Question
A centrifugal pump having four stages in parallel, delivers 12 kiloliters per minute of liquid
against a head of 25m. The diameter of the impeller being 24cm and a speed of 1800rpm. A
pump is to be made up with a number of stages in series. In similar construction to that of the first pump to run at 1250rpm and to deliver 15 kiloliter/min against a total head of 250m. Find the
diameter of the impellers and the number of stages required in this case.
The most common condition is that of pumping water from a sump, as illustrated
diagrammatically in figure below. Data: Water temperature 90°F., sea level, friction and
turbulence loss in the suction line 1 ft., suction lift 8 ft. What is the available suction head? The
vapor pressure corresponding to 90°F is 0.698lb. per sq. in. abs. and the specific gravity is 0.997.
per sq. in. abs. and the specific gravity is 0.996.
