Абсолютную влажность определяют по формуле: где f — максимальное напряжение водяных паров при температуре влажного термометра мм рт. ст. ; t 1 — показания сухого термометра, °С; t 2 — показания влажного термометра, °С; 5 — барометрическое давление в момент определения, мм рт. ст. ; 0, 5 — постоянный психрометрический коэффициент.
