Using Figure above, calculate the brake horsepower of a pump using water with a density of 62.4 lbm/ft3 and a flow rate of 60 gal/min. What speed would be required for the pump characterized in figure above to achieve a flowrate of 65 gal/min? What is the brake horsepower of the pump at this new speed? State any assumptions you make.

(Note: please do not copy other's answers and answer this question completely! (e.g. calculate the speed and new brake horse power at 65 gal/min)
