Steam enters an adiabatic turbine at 1,000 psia and 900 F with a mass flow rate of 6 lbm/s and leaves at 5 psia. The isentropic efficiency of the turbine is 0.90. Neglect the kinetic and potential energy changes of the steam.

What is the quality at the isentropic exit state, 2s (X2s)?

What is the exit temperature of the steam (T2)?

What is the power output of the turbine?
