Question
Consider an ideal gas-turbine cycle with a pressure ratio across the compressor of 12:1. The compressor inlet is at 300 K, 100 kPa, and the cycle has a maximum temperature of 1327 oC with a regenerator having an effectiveness of 80%. Find (a) the air temperature entering the combustor and (b) the thermal efficiency of the cycle. Use cold air properties at room temperature (cp = 1.00 kJ/kg-K, k = 1.4).
