Often on TV or from the speakers of the radio we hear about the pressure and humidity. But few people know, which affects their performance and how certain of them affect the human body.

humidity is

Humidity is a characteristic of saturation of the atmosphere with water vapor. In different parts of the globe, its performance may differ dramatically. In nature, there is no air without water vapor. On Earth there is no place where I did zero relative humidity. So, in the Sahara desert – 25 per cent, in the Brazilian jungle – 90.

Relative humidity is the ratio of moisture in the atmosphere compared to the maximum possible at a given temperature or the degree of its saturation with water. That is, the figure tells you how many vapors still need to start the condensation process. Relative humidity is one of the most important characteristics of the environment.

The Absolute rate was measured in a 1 g/m3 or in millimeters of mercury. At the equator it is 20-30 g/m3, while in the Arctic and the Antarctic – 0,1-1.

Humidity for man

Humidity, the rate of which is for dwellings from 40 to 60 percent, clearly felt by man. The highest value it reaches in the summer when rainy weather: then the rate is around 80-90%.

humidity normal

Winter in the flats of Russians there is an absolutely opposite situation. Due to heating, the relative humidity decreases to as much as 15 percent. This is due to the increase in temperature from the heaters, which in turn causes an active evaporation of moisture from the surface of the body and furniture.

Humidity is often underestimated factor. If you desire this indicator to the minimum or maximum values, deteriorating human health: increased fatigue, reduced memory abilities and concentration. To stay in physical and mental tonus, it is necessary to provide optimum moisture content of the areas in which people live and work. For this there are special air-conditioning system.

The Evaporation of moisture from the skin also depends on humidity, which in turn determines the body temperature of the person and the state of his body. Favourable indicator for the life is 40-60%. It is this humidity contributes to well-being. This figure is artificially maintained in the compartments of the spacecraft.

pressure and humidityTools and methods define

To determine the saturation of air with water vapor, using special devices: psychrometers and hydrometers. The August psychrometer is a bar with two thermometers: wet and dry.

First wrapped with a wet cloth, which by evaporation cools its body. Based on the indications of the thermometers, the tables determine the relative humidity. There are a variety of hydrometers, their work can be based on weight, film, electrical or hairline, as well as a number of other principles. In recent years it has gained popularity integrated measurement sensors. In order to verify the accuracy of the measuring instruments used hydrostatic.
