When applying the lever rule, I can find results which are fairly close (like about 0.5% away from the printed result) from those the lecturer provided, but I am a bit skeptical because maybe it's some sort of coincidence? 0000009126 00000 n 0000005167 00000 n 26 25 rev2022.7.29.42699.

I see now he is referring to quality.

After I chose a preferred referee for a submitted paper, is it un ethical to drop an email to the referee saying that I suggested their name? Yes, they do, I'm just wondering if there is a rule of thumb to know when to go to steam tables and when to go to saturated water tables. If saturated steam is reduced in temperature (while retaining its pressure) it will condense to produce water droplets, even if it is still considerably above the boiling point of 100C at standard pressure . I think you have just got to check to see whether the entropy at the final pressure is going to be between that of the saturated liquid and the saturated vapor. 0000000016 00000 n 34 23 You will find the entropy for 600 C, 15 MPa, is 6.680.
