Chapter 8, Problem 8.47P

Consider an ideal gas-turbine cycle with the following details in Table 1. Table 1 No. of stages at compression No. of stages at expansion 2 2 Pressure ratio 3 T of air at compressor inlet T of air at turbine inlet 300 K 1200 K Analyse the back work ratio and compare the thermal efficiency of the cycle for these two cases: i. no regenerator is used ii. a regenerator is used with 75 percent effectiveness

(b) Derive an expression for thermal efficiency of ideal Brayton cycle

Example-1 A Brayton cycle operates with air entering the compressor at 100 kPa, 25 °C, a pressure ratio of 6, and a turbine inlet temperature of 800 °C. Determine the compressor work input, the turbine work, the work ratio, the heat rejection and the cycle thermal efficiency for equal turbine and compressor efficiency of 100%; 80%; 70%; and 60%. T
