(choose chapter or problem)

Tests on an adiabatic gas compressor yield values for inlet conditions \((T_{1}, P_{1})\) and outlet conditions \((T_{2}, P_{2})\). Assuming ideal gases with constant heat capacities, determine the compressor efficiency for one of the following:

(a) \(T_{1} = 300 K, \quad P_{1} = 2 bar, \quad T_{2} = 464 K, \quad P_{2} = 6 bar, \quad C_{P} /R = 7/2\).

(b) \(T_{1} = 290 K, \quad P_{1} = 1.5 bar, \quad T_{2} = 547 K, \quad P_{2} = 5 bar, \quad C_{P} /R = 5/2\).

(c) \(T_{1} = 295 K, \quad P_{1} = 1.2 bar, \quad T_{2} = 455 K, \quad P_{2} = 6 bar, \quad C_{P} /R = 9/2\).

(d) \(T_{1} = 300 K, \quad P_{1} = 1.1 bar, \quad T_{2} = 505 K, \quad P_{2} = 8 bar, \quad C_{P} /R = 11/2\).

(e) \(T_{1} = 305 K, \quad P_{1} = 1.5 bar, \quad T_{2} = 496 K, \quad P_{2} = 7 bar, \quad C_{P} /R = 4\).
