Hygrometer: Fig

Fig. A hygrometer Humidity It is the measure of water vapour present in a gas or environment. It is measured in relative, absolute humidity or dew point temperature. Absolute humidity (AH) is the mass of the water vapour present per unit volume. Relative humidity (RH) is the ratio of water vapour pressure actually present to water vapour pressure required for saturation at a given temperature. RH is dependent upon temperature. A hygrometer is used to indicate RH. Hygrometer instruments ...
