An air turbine operates with P₁ = 1200 kPa and T₁ = 1500 K at the inlet, an inlet area of A₁ = 0.1 m², an inlet velocity of V₁ = 15 m/s, an exit pressure of P₂ = 100 kPa, and an isentropic efficiency of n = 90%. Complete a thermodynamic analysis of the turbine, assuming the specific heats are constant with k = 9/7, by finding: (A) The temperature at the exit, T2, (B) the mass flow rate through the turbine, m, (C) the work produced by the turbine, Wr, and (D) the rate of entropy production in the turbine, Šgen. Plot the process on a T-s diagram and clearly label states 1, 2s, and 2. WT
