fluid mechanics lesson (calculating popa power)

Calculate the power of the pump required to pump the water in hp(1 BG = 550 lbf.ft / sec)? Density = 62.4 lbm / ft3 andViscosity = 1 cp. Water can send to a tank on a flow rate of 30ft3 / min. data: g = 32.2 ft / sec2, gc =32,174 lbm.ft / lbf.sec2, T = 20 degrees Celsius, Pumpefficiency = 0.80.
