Hello!

I am trying to use Aspen Hysys for calculating some properties for binary mixtures. Among other properties I would like to calculate speed of sound and joule thomson coefficient. Do you know how can I see the values of those properties?

Thank you in advance

normally these are available in a properties table but that may depend from version, check manual / help,

for stream properties you may consider also tools as Nist Refprop or Prode Properties

( I read that Aspen is distributing Refprop as part of their package and you may have it)
