• It is desired to predict the performance of a large centrifugal pump from that of a scale model one fourth the diameter. The model absorbs 20 HP when pumping under test head of 20 m at its best speed of 400 r.p.m. The large pump is required to pump against 60 m head. The following will be the speed of the pump
