hi,

was wandering if anyone knows where i will be able to find Cp data at pressures higher than 1 atm for Oxygen, nitrogen. Was needing as high as 9 atm.

thanks

I am not a thermodynamist, but I think that the Cp is not pressure dependant for ideal gas. It is temperature dependant.

Bob:

siretb is essentially correct. However, if we are talking academics instead of practicalities, then the variances in the Cp for Nitrogen can seen at:

You can obtain this free information for Oxygen and a variety of other gases as well by starting out at: http://webbook.nist....hemistry/fluid/

Select "View data in HTML table" as your option when seeking results and you will get a tabular listing that can easily be copied and pasted onto an Excel spreadsheet.
