Влажность воздуха. Определение влажности воздуха

Determining relative humidity using a psychrometer. Definition: Humidity is a quantity indicating the water vapor content of the air. To describe this perception, the term relative humidity was introduced. Definition: Relative humidity is a quantity indicating how far the vapor is from saturation. In other words, relative humidity, in simple terms, indicates the following: if the vapor is far from saturation, the humidity is low; if it is close, the humidity is high. A psychrometer is a more convenient and accurate device for measuring relative humidity. However, even without such a table, you can roughly determine the humidity using the following principle. If the readings of both thermometers are close to each other, then the evaporation of water from the wet surface is almost completely compensated by condensation, meaning the air humidity is high. Conversely, if the readings of the thermometers differ greatly, then evaporation from the damp surface prevails over condensation, and the air is dry and the humidity is low. Physics, 8th grade.
