Water enters the bottom of a hot water heater in a home at a velocity of 1.25 ft/s, a temperature of 60F, and a pressure of 45 psia. The fluid exits at a velocity of 1.00 ft/s, a temperature of 130F., a pressure of 43 psia, and a height 5 ft higher than the entrance. Assuming no heat is wasted, determine the minimum amount of energy required in Btu/lbm. (Note 778 ft lbr = 1 Btu)
