A horizontal coil of water is circulated through it, which is heated from the outside by high-temperature flue gases. While passing through the coil, water changes condition from liquid at 200 kPa and 80oC to vapour at 100 kPa and 1250C, depending on the pressure and temperature. The speed at which it enters is 3 ms-1, and the speed at which it exits is 200 ms-1. Calculate the amount of heat that has been passed through the coil per unit mass of water. The following are the enthalpies of the entrance and outflow streams: The energy input is 334.9 kJ kg-1, while the energy output is 2726.5 kJ kg-1
