Question:

The turbine in Problem 14.112 is adiabatic. Is it reversible, irreversible, or impossible?

In Problem 14.112

Ethene, C₂H₄, and propane, C₃H₈, in a 1:1 mole ratio as gases are burned with 120% theoretical air in a gas turbine. Fuel is added at 25°C, 1 MPa and the air comes from the atmosphere, 25°C, 100 kPa through a compressor to 1 MPa and mixed with the fuel. The turbine work is such that the exit temperature is 800 K with an exit pressure of 100 kPa. Find the mixture temperature before combustion, and also the work, assuming an adiabatic turbine.
