Q2 (35 polats) 600cm2/s of water at 320K is puniped in a 40mm t.d. pipe through a length of 150m in a horizontal direction and up through a vertical helght of 10m. In the pipe there is a control valve which may be taken as equivalent to 200 pipe diameters and odher pipe fitings equivalent to 60 pipe diameters. Also in the line there is a heat exchanger across which there is a loss in head of 1.5m of water. If the main pipe has a roughness of 0.0002m.whail power must be deliveredto ihe pump if the unit is 60% efficient? ( wam=1000kg/a3 ' prew =0.6103NN2 )
