What is a specific humidity?
Specific humidity is one way to measure the amount of moisture or water vapor that is suspended in the air. In this case, the specific humidity concerns a direct relationship between the amount of air loaded with water vapor compared to the dry air at a predetermined weight of the air above all. This is measured by taking the amount of water vapor and dividing the total air weight in a given amount to achieve a ratio or percentage result, usually expressed as a grams of water vapor per kilogram of air.
Specific humidity remains constant regardless of pressure or temperature unless the humidity is added or reduced from the matter. This differs from the relative humidity in that it changes with fluctuations in the environment. Thanks to this somewhat stable moisture measurement method, specific humidity is considered to be a very useful reading in the process of predicting weather changes in meteorology. Chemical engineering processes also calculate specific humidity to determine how Affects the result of the chemical reactionwhose. It is also used in mechanical engineering to test the level of building materials, such as prefabricated concrete.
Absolute humidity is a closely related concept. In absolute humidity, the weight ratio of water in total air or grams per cubic meter is compared, while with a specific humidity it is the weight of the water in the total air weight, grams per kilogram. The main difference between them is that the values of absolute humidity change as a volume and therefore the air pressure changes. The term absolute humidity can be misleading because it is a value that fluctuates with air pressure and is therefore referred to in British standards as volume humidity.
weather forecasts often refer to a specific humidity in the context of precipitation, because the water vapor has a saturated point in the air depreciation temperature and air pressure. If specific air humidity grows due toFor water evaporation entering the air from the ground or other sources and the temperature does not change, the air saturation point also approaches, which could lead to clotting. Relative humidity, dew point and other factors also apply to meteorological calculations. All are affected by changes in temperature and changes in air pressure based on the height of the area above or below the sea level.
