Brayton cycle efficiency API

Air-standard Brayton (gas-turbine) thermal efficiency η = 1 − 1/rp^((γ−1)/γ) from pressure ratio rp and specific-heat ratio γ, plus the isentropic compressor temperature ratio. Answers 'What is the efficiency of a gas turbine?', 'How does pressure ratio affect Brayton efficiency?'.
