I understand that I could assume that nitrogen is an ideal gas at that temperature and pressure but I was having trouble understanding what makes a gas ideal in the first place. Only thing I knew that I could relate to this problem was that there is a range in the compressiblity factor where the...
I see it now, with Pr and Tr, I can find what z is. And I can find Pr and Tr with the given information.
Thank you for your help, I understand this much better now.
Since the compressibilty factor is a unique function of reduced pressure and reduced temperature, that is the only information required for me to find z. Correct?
If fluids compared at reduced pressure and reduced temperature have about the same compressibility factor. I would have to find the actual pressure and actual temperature of the fluid (lets say He) I am comparing it to, then find out if helium at that pressure and temperature is an ideal-gas or...
Specific volume is the inverse of density. However, as you know, density changes with temperature. So I would need the density or specific volume at 27°C but I cannot find it in my ideal-gas properties for nitrogen table and cannot find it online.
I don't understand ideal gases conceptually well enough to get any useful information out of that. I already looked at that before I posted here.
But I believe I might have an answer for it. Since we need two independent properties to identify the state of the system, and pressure and...
Hello everyone. I stumbled across a problem while studying for my exam that I cannot confidently answer.
Can we assume nitrogen at the temperature of 27˚C and the pressure of 100 kPa an ideal gas? Justify your answer.
The definition of an ideal gas is "...a gas whose molecules are spaced far...
I'm practicing integrals right now and came up on a question I have not seen before nor can I find online.
Integral from 0 to 1 of (x^e + e^x) dx
I'm stumped on x^e.
