Density of solution: 1100 kg/m3 Heat Capacity: 5.0 KJ/KgC The ideal concentration of brine is 20 kg/m3 and is at a syeady state. Throught a boiler pump, the solution is taken from the a tank at 50C and 1 bar absolute and it is delivered at 150C and 12 bar. The heat loss duryinf the process is 4 kJ/kg. 1. Write energy balance equation and its assumptions. 2. Calculate the work input to the pump in kJ/kg of solution passing through it
