pressure-temp chart for hydrogen in PSIG and deg. F

[joeywpittman]

i am looking for a pressure-temp chart for hydrogen in PSIG and deg. F
i am trying to condense hydrogen into a liquid by compressing it to xxxx psi and then cooling it xxxx degrees. but i would like a chart in imperial conversions.

Is Temperature in K vs entropy in cal/gm K acceptable?

See ASHRAE Fundamentals volume 1977 chapter 16 page 16.58.

ASHRAE got it from

National Bureau of Standards Research paper RP1032 (1948) by Wooley,Scott and Brickwedde, Fig 31.

IMO when it comes to thermodynamic charts you have to make do with the limited types of charts that are available - the only other option is to plot your own.
