The pump with mechanical efficiency 75% is used to flow Xylene at 20⁰C through the system with the rate of 13.8 m3/hr. The reservoir is at atmospheric pressure. The absolute pressure at the end of the discharge line is 425 kPa. The discharge line is 1.95 m above the pump, while the pump suction is 1.24 m above the level in the reservoir. The discharge line is 2.5-in. Schedule 40 steel pipe. The head friction in the discharge line is 5.73 m and in the suction line is 0.65 m. The vapor pressure of xylene at 20 oc is 0.655 kPa.

1. Calculate the total power input for this system.
2. Evaluate whether the pump is suitable for this system when the pump manufacturer specifies a Net Positive Suction Head Required (NPSHR) of 8.59 m. Justify your answer.
