Solution:

Pseudocritical pressure = 668 psia 4.54 MPa

Pseudocritical temperature = 389.14 R 255.69 K

Uncorrected gas viscosity at 14.7 psia = 0.011957 cp 1E-05 Pa-s

= 0.000000 cp 0 Pa-s

= 0.000000 cp 0 Pa-s

= 0.000000 cp 0 Pa-s

= 0.011957 cp 1E-05 Pa-s

Pseudo-reduced pressure = 6.91 6.91Pseudo-reduced temperature = 1.64 1.64

= 1.238702 1.24

Gas viscosity = 0.025091 cp 3E-05 Pa-s
