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 24 cm and a speed of 1800 rpm. A pump is to be made up with a number of stages in series. In similar construction to that the first pump to run at 1250 rpm and to deliver 15 kiloliters/min against a total head of 250m. find the diameter of the impellers and the number of stages required in this case.
