Helium at 800 kPa, 600 degree celcius enters a steady flow turbine and leaves at 100 kPa. The helium undergoes an expansion process through the turbine, does work in the amount of 900kJ/kg, and looses 50 kJ/kg of energy by heat transfer to the surroundings.

(A) determine the exit temperature of the helium in degrees celcius

(B) if the surroundings have a temperature of 25 degrees what is the total entropy change for this process?

(C)comment on your answer to part(B) is this process possible?

(D) Determine the exergy change of the steam during this process and the maximum work that the steam could have done.
