Tests on an adiabatic gas turbine (expander) yield values for inlet conditions (T1, P1) and outlet conditions (T2, P2). Assuming ideal gases with constant heat capacities, determine the turbine efficiency for one of the following:

a. T1 = 500 K, P1 = 6 bar, T2 = 371 K, P2 = 1.2 bar, Cp/R = 7/2
b. T1 = 450 K, P1 = 5 bar, T2 = 376 K, P2 = 2 bar, Cp/R = 4.
c. T1 = 525 K, P1 = 10 bar, T2 = 458 K, P2 = 3 bar, Cp/R = 11/2.
d. T1 = 475 K, P1 = 7 bar, T2 = 372 K, P2 = 1.5 bar, Cp/R = 9/2.
e. T1 = 550 K, P1 = 4 bar, T2 = 403 K, P2 = 1.2 bar, Cp/R = 5/2.
