A gas-turbine power plant operating on an ideal Brayton cycle has a pressure ratio of 8. The gas temperature is 300 K at the compressor inlet and 1300 K at the turbine inlet. Draw the Cycle on T-s and determine the thermal energy in the following cases
a) Isentropic process for compressor and turbine
b) 80% isentropic efficiency for compressor and turbine
