it is a single stage Tescom 1200 series Dome Loaded Regulator. Flowrate about 70cubic metres/min (at 1 atm) Jamie

starting temperature will be 0deg C. Before asking the question I did the T1/T2 = (P2/P1)^(1-k)/k calc giving me T2=113K. When colleagues expressed disbelief that it would be so cold, I had a re-think and realised that isentropic expansion was probably not the correct process for this. I...

I am struggling trying to calculate the temperature of the outlet air from a regulator which is reducing from 350 bar to 17 bar. I have read a long thread from this forum on a related subject but can't apply it to my problem. Can anyone help. thanks Jamie

thanks, I may well reduce the thickness J.
