It is proposed to design and develop a Rankine cycle Steam Power Plant in which steam at 80 barand 500 oCis supplied to the turbine which exhausts at a pressure of 0.11 bar into a condenser. Condensate from the condenser is returned to Steam Generator (Boiler) by a Feedwater Pump. The processes in the turbine and pump can be assumed to be reversible adiabatic. In addition, pressure and temperature drops can be neglected throughout the cycle. Sketch the T-s diagram for this cycle and calculate the following performance parameters:i) Cycle Thermal Efficiency ii) Work Ratioiii) Specific Steam Consumptioniv) Condenser Heat Loadv) Mass flow rate of steam to generate a net power output of 40 Megawatts (MW).vi) Mass flow rate of cooling water required for the condenser if the cooling water inlettemperature is 26 oC and its outlet temperature is limited to 40 oC. The specific heat capacityof the cooling water is 4.18 kJ/kg K.viii) The total amount of sensible heat in kW supplied to the…
Please state assumptions and tables.
Find the following:
a. Enthalpy of the steam in kJ/kg entering the condenser
b. Enthalpy in kJ/kg of the condensate
c. Enthalpy in kJ/kg of the feed water

A regenerative air cooling system is used for an air plane to take 20 tonnes of refrigeration load. The ambient air at pressure 0.8 bar and temperature 10°C is rammed isentropically til the pressure rises to 1.2 bar. The air bled off the main compressor at 4.5 bar is cooled by the ram air in the heat exchanger whose effectiveness is 60%. The air from the heat exchanger is further cooled to 60°C in the regenerative heat exchanger with a portion of the air bled after expansion in the cooling turbine.
