Question

A 1050 kPa-boiler is rated at 77,000 kW in a Rankine cycle at which the turbine’s pressure in the cycle is reduced to 20 kPa.  The condensation of the saturated steam is carried out using cooling water (Cp=4.18 kJ/kg °C) which enters the condenser at 14°C and leaves it at 88oC .

Determine:

  1. the turbine’s inlet temperature (in K)                                                                         
  2. the thermal efficiency of the cycle using the net amount of work of the cycle.      
  3. The flow rate of the cooling water (kmol/s)                                                             

Number the cycle clockwise with the turbine’s inlet stream as state 1
