Steam at 550 lbf/in.2, 700oF enters a turbine operating at steady state and exits at 1 lbf/in.2. The turbine produces 500 hp. For the turbine, heat transfer is negligible as are kinetic and potential energy effects.

 

a) Determine the quality of the steam at the turbine exit, the mass flow rate, in lb/s, and the entropy production rate, in Btu/s.oR, if the turbine operates without internal irreversibilities. (b) Plot the mass flow rate, in lb/s, and the entropy production rate, in Btu/s.oR for exit qualities ranging from the value calculated in part (a) to 1.
