Moin all,

I have programmed a function block to calculate the effective power of a compressor for a natural gas pipeline which I would like to check. Some of the real gas data which I have used seem rather unprecise.

Good values to check are the real specific heat capacity or entropie of CH4 at a temerature of 5 and 40 C and at a pressure of 30 and 90 bara. Four values from another source would help. The more values within this range the
better. Possibly for other components of natural gas too.

Anybody out there who has such values at hand or direct me to a web-site which has them?
