An adiabatic gas turbine receives a steady stream of air at 700 degrees Celsius and 1 MPa and exhausts it at 0.15 MPa. Velocities at inlet/outlet are negligible and specific heats are Cp= 1.0965 and Cv= 0.80779 KJ/Kg-K. a.) if process is isentropic determine the specific work produced (KJ/kg) b.) if the turbine work is 70% of the isentropic value determine the increase in entropy (KJ/kg-K) between inlet-outlet.
