The Milano ME laboratory has installed a double-suction, three-stage, centrifugal pump with a discharge of 330 gpm under 200 ft head and running at 1200 rpm. It is proposed to install another pump with double suction and six stages, but of the same characteristics, to operate at 98 ft head and deliver 430 gpm. Calculate: a) the speed of the proposed pump b) the impeller diameter of the proposed pump if the diameter of the existing pump is 6 inches; and c) the type of the existing and the proposed pump.

A certain centrifugal pump was tested and its performance curves can be approximated as follows: H = 340 - 1.2(Q2), in feet BP = (0.0521Q3) + (1.25Q2) + (11.042Q) + 134.5, in horsepower where Q is in ft3/s. If two of this pump is connected in series to deliver water to a system whose head requirement is 615 ft, what will be the operating discharge rate in ft3/s of either pumps? Assuming the head is equally divided between the two pumps, what is the efficiency of either pumps (in %)? Take the specific weight of water to be 62.4 lbf/ft3.
The original design of a hydraulic turbine has data as follows: flow rate of 1 cumex, effective head of 50 m, and runner diameter of 1.5 m. If the same turbine design is to be used in another application where the available flow is 2.5 cumex and effective head is 75 m, what would be the runner diameter (in meters) for this new application?
