Unformatted text preview: enters the ﬁrst compression stage at 300 K and 1 atm, and is compressed to 3 atm. The air is then cooled in the intercooler to 310 K, followed by the second compression stage to 9 atm. The air leaves the combustor at 1400 K, and a single turbine is used to expand the air. The regenerator has an eﬀectiveness of 0.9, both compressor stages are isentropic, and the turbine has an isentropic eﬃciency of 0.85. The engine produces a net power output of ˙ W =2 MW. Calculate the volumetric ﬂow rate of air entering the cycle and the cycle thermal eﬃciency. Assume constant speciﬁc heats. 1...
