1. The problem statement, all variables and given/known data A flue gas is cooled from 1100 C to 150 C and the heat is used to generate saturated steam at 100 C in a boiler. The flue gas has a heat capacity given by CP/R = 3.83 + 0.000551 T, where T is in K. Water enters the boiler at 100 C and is vaporized at this temperature. Its latent heat of vaporisation is 2256.9 kJ/kg. What is the lost work of this process 2. Relevant equations 3. The attempt at a solution Basically i think i only need help in finding the rate of entropy generation of this qn. I believe i can finish the qn once i get that :) I managed to equate mdot(steam) x ndot(gas) = -15.13g/mol by doing a simple energy balance Tried to sub that into equation for summation of entropy but cant seem to solve it. Sdot(g) = Sdotg(steam) + Sdotg(gas) I have calculated ΔS(gas) and ΔS(steam) to be -41.835 and 6048 J/kgK but still cant seem to sub it in. Appreciate the help!! Thks!!
