Discussion

• Without going through tedious calculation, can you estimate roughly the thermal efficiency of the first Rankine system (without superheating) will be? Does this estimated value close to the calculated one (35.3%).

• By increasing the condensing pressure from 0.01 MPa to 0.1 MPa, what do you think the thermal efficiency of the system will vary based on this change?

• Can you estimate the change (order of magnitude estimation) without going through calculation.

• Based on our calculation, the thermal efficiency actually decreases from 35.3% to 33.8%. Is this value consistent with your estimation? Why and why not?
