Would the Carnot theorem be useful?

That looks very inaccurate, given an error margin would be amplified at each stage over so many stages required. The ratio is 1.87 at 800K, 100 bar, that is a huge difference. Isn't there a way to find the corresponding P1, T1, P2, T2 from matching the properties from the table? Something like...

The best solution I have so far for solving for temperature from pressure is this: T1V1Cp/Cv-1=T2V2Cp/Cv-1 I would be find with solving anyone of the Temperature, Power and Pressure given one other. That formula, however, assumes that Cp and Cv are constant and thus only gives an...

Do you mean that each compressor has its own inefficiencies due to factors related to how they work, or that the theoretical power required for compressing the gas depends on the nature of the force compressing that gas? The first makes sense to me, but I don't see how the second one can make...

Wow, it looks like I used the density at boiling point from earlier calculation.:sorry: It works so much better with the right value. Now I get 1101.19, a difference of about 8%, which makes sense with the 61.79K difference between 1200K from the sheet and the actual temperature of 1261.79...

If the water is boiling, there is water vapor, and therefore no vacuum. So strictly speaking, it is not possible to boil water in a vacuum in the first place. If you are talking about "below atmospheric pressure", then let me use this analogy: If you take a sealed container with only water...

I am trying to find the theoretical power required to compress nitrogen from a pressure P1 to P2, as well as the final temperature T2 after compression. I found no formula that were anywhere near complete, but I found this tool, which tells me that from 300K@1Bar, I need 271.4kw (271kj/s) to...
