Question: 3 a gas turbine power cycle employs a twostage compressor...

Question details

3. A gas turbine power cycle employs a two-stage compressor with intercooling and a regenerator. Air 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.
