A gas mixture is analysed and found to contain 25% N₂, 35% O₂, and 40% CO₂ by volume. The pressure and temperature of the mixture is 120 kPa and 500 K respectively. This mixture undergoes an expansion process in an isentropic turbine to a pressure of 90 kPa. Treating the gas mixture as an ideal gas mixture with constant specific heats at 300 K, calculate; a) The Molar Mass and Gas Constant of the mixture. [3 marks] b) The temperature of the mixture after expansion. [4 marks] The work output per kg of the mixture in the turbine. [3 marks] Answer:
