1200 cm³/sec of water at 420 K is pumped in a 40 mm internal diameter pipe

through a length of 150 m in a horizontal direction and up through a vertical length of 10 m . In the pipe there is a control valve which may be taken as equivalent to 200 pipe diameters and other pipe fittings equivalent to 60 pipe diameter. Also in the line there is a heat exchanger across which there is a loss in head of 1.5 of water. What power must be delivered to the pump if the unit is 60% efficient?

PS: roughness factor not given
