Use the Compressed Air Dew Point Calculator to calculate dew point from temperature and relative humidity. The calculator uses Air temperature and Relative humidity and reports atmospheric dew point.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are atmospheric dew point. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Pw=RH·Pws(T)/100; dew/frost point is numerical inverse T such that Pws(T)=Pw using Vaisala/Hyland-Wexler water/ice equations. The functional engine is shared with related tools in the humidity family, while this page solves the specific intent represented by compressed air dew point calculator.
Pw=RH·Pws(T)/100; dew/frost point is numerical inverse T such that Pws(T)=Pw using Vaisala/Hyland-Wexler water/ice equations.Reproducible example: start with the calculator's default values (Air temperature = 20; Relative humidity = 50) and calculate the result. Then change the variable most relevant to your application and compare the new atmospheric dew point against the baseline.
RH must be 0–100%; at very low Pw return bounded dry-limit message if outside validated inversion range.
It is designed to calculate dew point from temperature and relative humidity. The reported outputs are atmospheric dew point.
The calculator uses Air temperature and Relative humidity. Only use values that represent the same operating condition or design case.
The calculation follows: Pw=RH·Pws(T)/100; dew/frost point is numerical inverse T such that Pws(T)=Pw using Vaisala/Hyland-Wexler water/ice equations. The page also states the assumptions that define where the method is valid.
RH must be 0–100%; at very low Pw return bounded dry-limit message if outside validated inversion range.
Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
