solution

Compare the results of Problem 8.26 with those for an ideal Rankine cycle having the same turbine inlet conditions and condenser pressure, but no regenerator

Modify the ideal Rankine cycle of Problem 8.7 to include one open feedwater heater operating at 100 lbf/in.2 Saturated liquid exits the open feedwater heater at 100 lbf/in.2 The mass flow rate of steam into the first turbine stage is the same as the mass flow rate of steam in Problem 8.7. Answer the same questions about the modified cycle as in Problem 8.7 and discuss the results.

Reconsider the cycle of Problem 8.28, but include in the analysis that the isentropic efficiency of each turbine stage is 88% and of each pump is 80%.
