You will get fast and accurate psychrometric calculations of a single moist air.
The state of moist air is shown by pressure, dry-bulb temperature, relative humidity, specific enthalpy, specific volume bulk, etc.
These values can be calculated if each expression of relations shows three values.
Usually, since pressure is used under normal atmospheric pressure in many cases, if this is set constant and two status values are given, it can calculate other values by calculation.
By using this program, each status value read in the psychrometric diagram can usually be calculated easily.
Use of the range of dry-bulb temperature DB-20℃ to 90℃ is assumed.
Even if it exceeds this domain, calculation may be possible, but the error will be larger.
