An air standard gas turbine engine has a compressor pressure ratio of 12.  It operates between 290 K and 1400 K.  The turbine and compressor each have isentropic efficiencies of 90%. Determine the following:

a)  Net work per unit mass of air flow.

b) Heat rejected per unit mass flow of air.

c)  Thermal efficiency.
