Question:

A steady-flow adiabatic turbine (expander) accepts gas at conditions T1, P1, and discharges at conditions T2, P2. Assuming ideal gases, determine (per mole of gas) W, Wideal, Wlost, and So for one of the following cases. Take T( - 300 K?
(a) T1 = 500 K, P1 = 6 bar, T2 = 371 K, P2 = 1.2 bar, C P / R = 7/2.
(b) T1 = 450 K, P1 = 5 bar, T2 = 376 K, P2 = 2 bar, C P / R = 4.
(c) T1 = 525 K, P1 = 10 bar, T2 = 458 K, P2 = 3 bar, C P / R = 11/2.
(d) T1 = 475 K, P1 = 7 bar, T2 = 372 K, P2 = 1.5 bar, C P / R = 9/2.
(e) T1 = 550 K, P1 = 4 bar, T2 = 403 K, P2 = 1.2 bar, C P / R = 5/2.
