Homework Statement
Determine the volume, in m^3, occupied by 20 kg of hydrogen (H2) at 1170 kPa, 2220°C.
Homework Equations
Z=pv/rt, Pr=P/Pc, Tr=T/Tc, and for hydrogen M = 2.016 (kg/kmol) Tc = 33.2 (K) Pc = 13.0 bar Zc=pc*vc/(RTc)
The Attempt at a Solution
I know if I find Z then the problem is a done deal. I'm just confused about how to use Pr,Tr, and the table to find Z. I found Pr=.9 and Tr=1.59 but is there a formula for Z?
Thanks in advance for the help (I'm not a fan of Thermo so far and my Profs at my old college spoiled me with great teaching)
