2) Mixture expansion A reversible, adiabatic turbine expands an ideal gas mixture from T = 1500 K, p = 12 bar to 1 bar with a flow rate of 2.3 kmol/s. What is the rate of work production and the exit temperature if the gas mix is (mole fractions): 73.9 % N2, 6.5 % O2, 73.9 % N2, 10.9% H2O, 8.7% CO2. {Some iteration is needed. Hint: to estimate the exit temperature at first, assume dry air.}
