Water flows through a horizontal coil heated from the outside by high-temperature flue gases. as it passes through the coil the water changes state from liquid at 200 kpa and 80 degree c to vapor at 100 kpa and 125 degree c. its entering velocity is 3 ms^-1 and its exit velocity is 200 ms^-1. determine the heat transferred through the coil per unit mass of water. enthalpies of the inlet and outlet stream are: inlet: 33.4.9 kj kg^-1 ; outlet: 2,726.5 kj kg^-1
