Question 1 Nitrogen at 3 MPa and 300C is expanded in an adiabatic, reversible gas turbine to 0.5 MPa. Assume nitrogen has constant specific heats. Determine a. The final temperature and b. The maximum work for this turbine. The specific heats of Nitrogen are cv = 0.752 kJ/kg.K, Cp = 1.049 kJ/kg.K and the specific heat ratio k = 1.395 according to the average temperature. 3 MPa, 300C 0.5 MPa Your
