A gas turbine operates as a cold-air standard Brayton cycle. Airenetrs the compressor at 300K and 100kPa and is compressed to700kPa. During the heat addition process in the combustor, thetemperature of the air increases to 1000K. The turbine andcompressor can be assumed to be operating isentropically. Evaluatespecific heat at 300K.
a. thermal efficiency of the cycle?
b. net work of the cycle (kj/kg)?
c. Back work ratio?
