LAB-EL HUMIDITY CALCULATOR computer program was designed for basic calculation of humidity measurements. This kind of calculations are often required in meteorology, when designing air conditioning systems, during manufacturing processes as well as in laboratories (e.g. when calibrating measurement equipment). This program allows users to convert one set of humidity parameters into another.

LAB-EL HUMIDITY CALCULATOR computer program calculates uncertainty results. These are taken from uncertainty of input data (introduced by the user through the input window) and the uncertainty of formula used for moisture calculation.

The results are true with respect to over water or to over ice, depending on whether there is water or frost (ice) in the chilled mirror hygrometer or psychrometer.

The input and counted data values are as follow:
DP - dew point temperature,
FP - frost point temperature,
RH - relative humidity with respect to water (or to ice),
T - air temperature,
Tw/Ti - the wet-bulb (or ice-bulb) temperature in psychrometer,
P1 - air pressure at point 1, where input values are defined,
P2 - air pressure at point 2, where values are calculated,
PPMV - volume of water vapour in dry air (ppm, parts per million),
PPMW - mixing ratio, weight of water vapour in dry air (ppm, parts per million),
x - mixing ratio, weight of water vapour in dry air (g/kg),
I - enthalpy I(1+x) of mixture dry air (1) and water vapour (x),
WVP - vapour pressure in moist air,
SWVP - saturation vapour pressure of moist air with respect to water (or to ice).



Program KALKULATOR WILGOTNOSCI LAB-EL pozwala na prowadzenie przeliczen roznych parametrow opisujacych klimat. Obliczenia takie wykonuje sie np. w meteorologii, przy projektowaniu klimatyzacji pomieszczen, w procesach technologicznych w przemysle oraz w laboratoriach metrologicznych (np. podczas prowadzenia wzorcowania przyrzadow pomiarowych). Znajomosc okreslonego zestawu danych wejsciowych umozliwia obliczenie pozostalych parametrow klimatu.

Program KALKULATOR WILGOTNOSCI LAB-EL oblicza niepewnosci wynikow, ktorych zrodlem sa zarowno niepewnosci danych wejsciowych (wprowadzane przez uzytkownika w ramce danych wejsciowych), jak i niepewnosci wzorow wykorzystanych do obliczen wilgotnosci.

Wyniki obliczen sa wazne odpowiednio w kolumnie Nad woda albo Nad lodem w zaleznosci od wystepowania wody albo szronu (lodu) w higrometrze punktu rosy lub psychrometrze.

Mozliwe jest wprowadzanie i obliczanie nastepujacych wielkosci:
DP - temperatura punktu rosy,
FP - temperatura punktu szronu,
RH - wilgotnosc wzgledna odniesiona do stanu nasycenia nad woda (lub lodem),
T - temperatura powietrza,
Tw/Ti - temperatura termometru mokrego pokrytego woda (lub lodem) w psychrometrze,
P1 - cisnienie powietrza panujace w punkcie 1, w ktorym sa okreslone wprowadzane dane wejsciowe,
P2 - cisnienie powietrza panujace w punkcie 2, w ktorym sa obliczane wyniki,
PPMV - zawartosc objetosciowa pary wodnej w suchym powietrzu (ppm, czesci milionowych),
PPMW - zawartosc wilgoci, stosunek masy pary wodnej do masy suchego powietrza (ppm, czesci milionowych),
x - zawartosc wilgoci, stosunek masy pary wodnej do masy suchego powietrza (g/kg),
I - entalpia I(1+x) mieszaniny powietrza suchego (1) i pary wodnej (x),
WVP - cisnienie pary wodnej znajdujacej sie w wilgotnym powietrzu, cisnienie czastkowe pary wodnej,
SWVP - cisnienie nasyconej pary wodnej zawartej w wilgotnym powietrzu nad woda (lub lodem).
