The dew of Compressed air usually is concerned by us.
But we only can measure the dew of atmosphere pressure air.
So how the dew of atmosphere pressure air convert to Compressed air's? Are there some graphs or tables or formulas for it?
Thank you in advance.

Dear all,

When you use the DEW POINT CONVERSION CHART, please be careful...

I guess Padmakar has downloaded it from

compressed-air-dewpoint

Look at the ATMOSPHERIC line, temperature range
- from 80degC to 130 degC and
- from -100 degC to -50 degC,

looks OK...

However, from -50 degC to 80 degC, they are "out". Probably this is due to "scan-and-match" porblem. This has created some doubt on the accuracy on other lines and reading.

Somehow, you may use it for quick reference.

Dear Buddy Joe,
Thanks a lot dear. Your have a genius mind no doubt.I have checked this.I am thankful for your suggestion.


Dear Daiweisc,
Already you wanted any graph,formula or theory now you got everything so go for hand calculations and make the required program to avoid the same repetative calculations don't depend so much on the softwares for everything.I hope you will not mind for my this suggestion.
