The pressure ratio of a Brayton cycle with air operated
regenerator is 8. The lowest and highest temperatures of the cycle
are 310 K and 1150 K. The adiabatic efficiency of the compressor
and turbine is 75% and 82%, respectively, and the efficiency of the
regenerator is 65%. Show the cycle in the T-s diagram. Consider the
variation of specific temperatures with temperature.
a) Calculate the temperature of the air at the turbine
outlet,
b) Net work of the cycle,...
