On the conversion of atmospheric dew point and pressure of compressed air

In the compressed air purification industry and industries that use compressed air, it is common to encounter the problem of converting the atmospheric dew point of compressed air to pressure.

Many literature have provided conversion curve graphs for this. However, there are some inconveniences in using these curve charts for dew point conversion:;

1. The unit of pressure in some conversion curve graphs is kgf/cm2, not the legal measurement unit MPa or its multiples;

2. The conversion curve can only provide the function curve of atmospheric dew point and pressure dew point under integer multiples of pressure units. When it is necessary to convert atmospheric dew point to dew point under other pressures, it is very inconvenient;

3. These conversion curve graphs are not large in size, making it very difficult to obtain accurate readings.

Furthermore, the accuracy of these curves themselves is also questionable

Given the above reasons, if the conversion problem between atmospheric dew point and pressure dew point can be solved through calculation or with the help of calculation, it will be very convenient for relevant personnel in the compressed air purification industry and the industry that uses compressed air.
