A small model of a water pump with an impeller diameter of 8 in is able to develop a head of 15 ft and flow of 100 GPM when spun at 1200 RPM with a power input of 0.4 hp. If a larger model of the same pump with an impeller diameter of 24 in is to be used for another application where the required head is 80ft, at what speed (in RPM) should this larger model be ran, and at what capacity (in GPM) can it deliver water?
