Please answer a,b,c. Badly needed. Thank you.
Figure shows the schematic diagram of a cogeneration cycle. In the steam cycle, superheated vapor enters the turbine with a mass flow rate of 5 kg/s at 40 bar, 440°C and expands isentropically to 1.5 bar. Half of the flow is extracted at 1.5 bar and used for industrial process heating. The rest of the steam passes through a heat exchanger, which serves as the boiler of the Refrigerant 134a cycle and the condenser of the steam cycle. The condensate leaves the heat exchanger as saturated liquid at 1 bar, where it is combined with the return flow from the process, at 60°C and 1 bar, before being pumped isentropically to the steam generator pressure. The Refrigerant 134a cycle is an ideal Rankine cycle with refrigerant entering the turbine at 16 bar, 100C and saturated liquid leaving the condenser at 9 bar. Determine, in kW, (a) the rate of heat transfer to the working fluid passing through the steam generator of the steam cycle. (b) the net power output of the binary cycle. (c) the rate of heat transfer to the industrial process. -Steam generator Turbine 15 har To industrial H,0 cycle process H,O/R-134a heat exchanger Turbine Refrigerant cycle R-134a cycle Pump Condenser Pump Return flow from industrial process I har, 60°C
