A simple ideal Brayton cycle with air as the working fluid has a pressure ratio of 10. The air enters the compressor at 520 R and the turbine at 2000 R. Accounting for the variation of specific heats with temperature. Determine:
a. the air temperature at the compressor exit
b. the back work ratio (work consumed by compressor/work output from turbine)
c. the thermal efficiency.
