A mixture of O2, CO, and He gases with mass fraction of 0.0625, 0.625, and 0.3125 respectively enter an adiabatic turbine at 1000 kPa and 600 K steadily and expand to 100 kPa pressure. The isentropic efficiency of the turbine is 90%. For gas components assuming constant specific heats at room temperature, determine: the work output per unit mass of mixture. Take the room temperature to be To = 25C. The specific heats of O, CO, and He gases are as follow Gas 0 CO He Cv [kJ/kg.K] 0.658 0.657 3.1156 Cp [kJ/kg.K] 0.918 0.846 5.1926 1000 kPa 600 K O2, CO, He mixture 100 kPa W
