A water main is used to refill an elevated storage tank during the night. a 100 ft long, 12 in steel pipe (ks=.06 mm) connects to the booster pump that provides a pressure of 75 psig at the pump outlet. the steel pipe outflows to a jet open to atmosphere at an elevation of 80 ft within the tank. determine the volume of water in gallons added to the tank over a 3 hour period, assuming that the outlet never becomes submerged. you may use the jain formulation.
