Example 6.12: Heat Exchanger (2)
The steam in the previous example is cooled using water at 1 bar, 25 °C. The cooling water emerges at 40 °C at the exit of the heat exchanger. Determine the heat load and the entropy generation. Compare the result with the previous example. Example 6.20: Rankine Plant
A Rankine power plant using steam operates between pressures 60 bar and 1.013 bar. The turbine expands steam from 500 °C, 60 bar, to 1.013 bar. The liquid at the exit of the condenser is saturated. The efficiency of the turbine and of the pump is 75%. Calculate the energy balances, entropy generation, and thermodynamic efficiency. What are the sources of irreversibility?
