Simple flow works according to the simple Brayton cycle. The air enters the compressor with 80 kPa pressure, 280 K temperature and 55 m3 / h volumetric flow. The pressure ratio in the compressor is 20, the maximum temperature in the cycle is 2100K. As the compressor will have an isentropic efficiency of 93%, a turbine of 96% and a cold air standard.
a) Net power, MW
b) Heat transfer in the boiler, MW
c) Thermal efficiency of the cycle
d) If it is considered to use heat transfer at 2500 K temperature, find the entropy production in the boiler by writing the 2nd law (entropy balance).
