23PRACTICE PROBLEM
A spacecraft propulsion system operates using a Brayton cycle with the following processes: (1-2) adiabatic compression, (2-3) isobaric heating, (3-4) adiabatic expansion, and (4-1) isobaric cooling. The gas mixture behaves as an ideal gas with a heat capacity ratio γ=1.4. Derive the expression for the efficiency e of this Brayton cycle in terms of the pressure ratio P2/P1 and γ.
