Ok, I feel really bad about this, the T value is -220 °C, which makes the Tr come out to 53.0K/33.2k=1.59. Pr=.900 with the correct number of sig. figs. After reading the question twice more, looking for something about how to approximate Z, i finally found the attached chart hiding in the back...
Sadly no, Z is the factor that relates PV/RT of Hydrogen to the PV/RT of and ideal gas. Hydrogen in this problem, because of the high temperatures and pressure, is not an ideal gas.
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...
