The August station psychrometer consists of two identical alcohol thermometers, the reservoir of one of which is wrapped with a piece of thin hygroscopic tissue, dipped at one end in a glass of distilled water at

Calculation of absolute humidity using the Assman psychrometer is carried out according to the Springs formula: K = f – 0.5 (t – t 1 ) • 755 The calculation of absolute humidity when working with the August

The hygienic significance of air movement consists, first of all, in that it promotes ventilation (aeration) of residential quarters and the buildings located there, leads to the very purification of the atmosphere from pollution. In addition, the wind provides the transfer of heat

The determination of air velocity in excess of 0.5 m / s is carried out using anemometers (from the Greek. Anemos – wind). In sanitary practice, dynamic anemometers are used, based on the rotation of light

Knowing the value of the cooling ability of the catheter and the ambient temperature, it is possible empirically Arrow indications The difference in readings is 5680 m – 4200 m = 1480 m The desired air

The basis of a hygienic assessment of the influence of microclimatic conditions should be based on its final effect. The effect can be considered positive if it helps to maintain the temperature constancy of the body,
