Benzene, p= 54 lb/ft^3 at 100 F is pumped at a rate of 40 gpm. The reservoir is open to atmosphere and below the pump centreline by 4 ft. The discharge line is 10 ft above the pump centreline. The gage at discharge reads 50 psig. The discharge line is 1.5 in in diameter. The suction line and discharge line losses are 1.16 ft and 12.7 ft respectively. Calculate the developed pump head and the total power input
