A turbine operates adiabatically with super-heated steam entering at T1, and P1, with a mass flow-rate, m(dot). The exhaust pressure is P2 and the turbine efficiency is gamma. For one of the following sets of operating conditions determine the power output of the turbine and the enthalpy and entropy of the exhaust stream. A) T1=450C, P1=8000kPa, m(dot)=80kg/s, P2= 30kPa, gamma=.80
