How to convert relative humidity to absolute humidity

Relative humidity is the ratio of absolute humidity to saturation humidity.

Absolute moisture content: relative humidity = absolute humidity of moist air The maximum absolute humidity that can be achieved at the same temperature.

The maximum absolute humidity that can be achieved at the same temperature needs to be checked in the meter.

Standard atmospheric pressure, temperature 35° relative humidity 50, find absolute humidity.

If it's 35, the absolute humidity is.

It is obtained by the Kraberon equation pv=nrt.

n=（pv）/rt

m=18n=(18pv)/(rt)

Check the water saturated vapor pressure gauge to get 35 times p=, t = 35 + generations of the above equation.

Absolute humidity is calculated by w=(em) [rw)· (tv)。 W is the absolute humidity, E is the vapor pressure, T is the temperature, the mass of water vapor contained in each cubic meter of moist air, i.e., the water vapor density, in kg m3.

Humidity is a physical parameter that characterizes the amount of water vapor in the atmosphere, and absolute humidity is one of the many ways to characterize humidity.

Under the condition of a certain air pressure and a certain temperature, there is a limit to the water vapor that can be contained in a unit volume of air, if the water vapor contained in the volume of air exceeds this limit, the water vapor will condense and produce precipitation, and the value of water vapor actually contained in the volume of air is expressed as absolute humidity. The higher the water vapor content, the higher the absolute humidity of the air.

Difference Between Absolute Humidity and Relative Humidity:

1. Absolute humidity refers to the amount of water vapor contained in a unit volume of air; In gram beams.

2. Relative humidity refers to the ratio of the actual water vapor content in the air to the saturation value water vapor content at a certain temperature, expressed in percentages.

3. Absolute humidity will not change with temperature and climate change, but relative humidity will change qualitatively with the increase of temperature and the decrease of temperature, usually the relative humidity will decrease with the increase of temperature.

4. The maximum amount of water vapor that can be absorbed by air with an absolute humidity of 1 cubic meter is called the maximum humidity or saturation point, and the maximum humidity depends largely on the temperature.

5. Absolute humidity refers to the density of water vapor in the air, and the weight (g) of water vapor in 1m air is expressed. The water vapor content is high, and the absolute humidity of the air is high. There is a limit to the amount of water in the air, and when it reaches its maximum capacity, it is called the saturated water vapor content.

It is the mass of water vapor contained in a unit of air, which is a physical expression of the degree of dryness and wetness of the atmosphere, usually expressed in grams of all water vapor in 1 cubic meter. Since the pressure of water vapor increases with increasing density, the absolute humidity segment of the air can usually be expressed as pressure.

Relative humidity is the percentage value of the actual water vapor density contained in the air and the saturated water vapor density at the same temperature. There is a relationship between the degree of dryness and wetness in the air and the amount of water vapor contained in the air that is close to saturation, while the absolute amount of water vapor in the air is not directly related to the amount of water vapor contained in the air.

Water vapor] Abbreviated as water vapor, it is a gaseous form of water (H2O), which turns into water vapor when it reaches its boiling point. At one standard atmosphere at sea level, the boiling point of water is or 212°F. Water can also slowly evaporate into water vapor when it is below the boiling point.

In a very low pressure environment (less than atmospheric pressure), ice will directly sublimate into water vapor. Water vapor may contribute to the greenhouse effect and is a type of greenhouse gas.

Relative humidity calculation method: (absolute humidity maximum humidity)*100%; (vapor pressure, saturation vapor pressure)*100%; (Specific Humidity Highest Specific Humidity)*100%.

Relative humidity refers to the percentage of the actual partial pressure of water vapor per unit volume of air and the saturated vapor pressure of water at the same temperature and volume as the stove purity. That is, the ratio between the absolute humidity and the most implicit high humidity, and its value shows how high the saturation of water vapor is.

Relative humidity is the amount of water vapor per unit volume of air as a percentage of its content when it reaches its saturation value.

Calculation formula: rh=PW PWS(t) 100% (where, PW: water vapor pressure; PWS(t): saturated water vapor pressure).

At a certain temperature, the ratio of the partial pressure of water vapor in the gas mixture to the vapor pressure of pure water at the same temperature is called the relative humidity of the gas mixture at this temperature.

Formula: hr=pa ps x 100%.
