Air enters an ideal gas turbine cycle at 1 bar and 27 C. The maximum temperature in the cycle is 727 C. Find the cycle efficiency for a compression ratio of 10.

Air enters the compressor of an air standard Brayton cycle at 27 C and 0.1 MPa. The cycle pressure and temperature ratios are given as
r_P

= 11 and
r_T

= 4, respectively. Find a) pressure and temperature at the end of each process, b) thermal efficiency, c) work per unit mass, d) cycle pressure ratio for optimum work, and e) the required mass flow rate to produce 1 MW power.
