Chapter 8, Problem 8.40P

Consider a simple ideal Rankine cycle and an ideal regenerative Rankine cycle with one open feedwaterheater. The two cycles are very much alike, except the feedwater in the regenerative cycle is heated byextracting some steam just before it enters the turbine. Compare the efficiencies of these two cycles. Showyour complete solution and diagram’s.

A  Carnot cycle has been chosen as a candidate for the ideal vapor power cycle.  The pump inlet is a saturated liquid and the minimum and maximum pressures are set.  The minimum pressure is 10 kPa and the maximum pressure is 10 MPa.  Check all that will are correct Group of answer choices The minimum pump work will be about 5 kJ/kg The efficiency of the Carnot cycle will be greater than the efficiency of a Rankine cycle with the same minimum and maximum pressures The difference between the maximum and minimum temperature will be small and the thermal efficiency will be low. The minimum pump work will be about 10 kJ/kg
