Consider a water-ammonia binary vapor cycle consisting. In the steam cycle, superheated vapor enters the turbine at 7 MPa, 450C, and saturated liquid exits the condenser at 55C. The heat rejected from the steam cycle is provided to the ammonia cycle, producing saturated vapor at 45C, which enters the ammonia turbine. Saturated liquid leaves the ammonia condenser at 1 MPa. For a net power output of 24 MW from the binary cycle, determine (a) the mass flow rates for the steam and ammonia cycles, respectively, in kg/s, (b) the power output of the steam and ammonia turbines, respectively, in MW. (c) the rate of heat input to the ammonia cycle, in MW, (d) the rate of heat addition to the binary cycle, in MW, and (e) the thermal efficiency of the binary vapor cycle.
