Q.5 A pump circulates water through a closed pipe network connecting a water heater and a heating coil (heat exchanger) in a room. The total length of the pipe is 28 m and the diameter is 32 mm. There are six 90°-elbows and a globe valve in the network. The head loss through the water heater and the heating coil are 1.6 m and 1.2 m respectively. The water flow rate is 0.88 Ls-!. The system uses schedule-40 steel pipes with threaded fittings. Calculate the (i) flow velocity and the unit pressure loss in the pipe. (ii) increase in head across the pump. (iii) power input to the pump if the efficiency of the pump is 70%.
