In a detergent-making process, 1400gal/h of water flows through a 2-inch pipe system as follows: Exit from the pump, 2ft vertical, open gate valve, 14 ft vertical, 908 bend, 12ft horizontal, 1/4 open globe valve, 20ft horizontal, 908 bends, 6ft horizontal, 908 bends, 12ft vertical, 908 bends, 14ft horizontal, 908 bends, 4 ft vertical, 908 bends, 28ft horizontal, open gate valve, 3ft horizontal, entry to a tank containing 30ft of liquid. 

(a). If the pump and tank are both at grade level, estimate the head that the pump must deliver.

(b). If the pump inlet pressure is 25 psig, what is the outlet pressure? 

(c). Estimate the pump shaft work

( d). If the pump is powered by an electric motor with 85% efficiency, what is the annual electricity consumption?
