humidity meaning in tamil

Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity depends on temperature and the pressure of the system of interest.

Questions Kids Ask Humidity

The same amount of water vapor results in higher humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass.

The amount of water vapor contained within a parcel of air can vary significantly. Three primary measurements of humidity are widely employed: absolute, relative and specific. Absolute humidity describes the water content of air and is expressed in either grams per cubic metre [2] or grams per kilogram. Specific humidity is the ratio of water vapor mass to total moist air parcel mass. Humidity plays an important role for surface life.

For animal life dependent on perspiration sweating to regulate internal body temperature, high humidity impairs heat exchange efficiency by reducing the rate of moisture evaporation from skin surfaces. This effect can be calculated using a heat index table, also known as a humidex. The notion of air "holding" water vapor or being "saturated" by it is often mentioned in connection with the concept of relative humidity. This, however, is misleading—the amount of water vapor that enters or can enter a given space at a given temperature is almost independent of the amount of air nitrogen, oxygen, etc.

Indeed, a vacuum has approximately the same equilibrium capacity to hold water vapor as the same volume filled with air; both are given by the equilibrium vapor pressure of water at the given temperature. Absolute humidity is the total mass of water vapor present in a given volume or mass of air. It does not take temperature into consideration. The absolute humidity changes as air temperature or pressure changes, if the volume is not fixed.

This makes it unsuitable for chemical engineering calculations, e. As a result, absolute humidity in chemical engineering may refer to mass of water vapor per unit mass of dry air, also known as the humidity ratio or mass mixing ratio see "specific humidity" belowwhich is better suited for heat and mass balance calculations.

Mass of water per unit volume as in the equation above is also defined as volumetric humidity. Because of the potential confusion, British Standard BS [9] suggests avoiding the term "absolute humidity". Units should always be carefully checked. The field concerned with the study of physical and thermodynamic properties of gas—vapor mixtures is named psychrometrics.

Relative humidity is normally expressed as a percentage ; a higher percentage means that the air—water mixture is more humid. Relative humidity is an important metric used in weather forecasts and reports, as it is an indicator of the likelihood of precipitationdew, or fog. In hot summer weathera rise in relative humidity increases the apparent temperature to humans and other animals by hindering the evaporation of perspiration from the skin. Specific humidity or moisture content is the ratio of the mass of water vapor to the total mass of the air parcel.

As temperature decreases, the amount of water vapor needed to reach saturation also decreases. As the temperature of a parcel of air becomes lower it will eventually reach the point of saturation without adding or losing water mass.

The term relative humidity is reserved for systems of water vapor in air. The term relative saturation is used to describe the analogous property for systems consisting of a condensable phase other than water in a non-condensable phase other than air.

A device used to measure humidity of air is called a psychrometer or hygrometer. A humidistat is a humidity-triggered switch, often used to control a dehumidifier. The humidity of an air and water vapor mixture is determined through the use of psychrometric charts if both the dry bulb temperature T and the wet bulb temperature T w of the mixture are known.

These quantities are readily estimated by using a sling psychrometer. There are several empirical formulas that can be used to estimate the equilibrium vapor pressure of water vapor as a function of temperature.The temperature is 67 degrees with humidity at 75 percent.

Although the principles of psychrometry apply to any physical system consisting of gas-vapor mixtures, the most common system of interest is the mixture of water vapor and air, because of its application in heating, ventilation, and air-conditioning and meteorology.

In human terms, our thermal comfort is in large part a consequence of not just the temperature of the surrounding air, but because we cool ourselves via perspiration the extent to which that air is saturated with water vapor. Many substances are hygroscopicmeaning they attract water, usually in proportion to the relative humidity or above a critical relative humidity. Such substances include cotton, paper, cellulose, other wood products, sugar, calcium oxide burned lime and many chemicals and fertilizers.

Industries that use these materials are concerned with relative humidity control in production and storage of such materials. In industrial drying applications, such as drying paper, manufacturers usually try to achieve an optimum between low relative humidity, which increases the drying rate, and energy usage, which decreases as exhaust relative humidity increases.

In many industrial applications it is important to avoid condensation that would ruin product or cause corrosion. Molds and fungi can be controlled by keeping relative humidity low. The dry-bulb temperature is the temperature indicated by a thermometer exposed to the air in a place sheltered from direct solar radiation.

The term dry-bulb is customarily added to temperature to distinguish it from wet-bulb and dew point temperature.

In meteorology and psychrometrics the word temperature by itself without a prefix usually means dry-bulb temperature. Technically, the temperature registered by the dry-bulb thermometer of a psychrometer. The name implies that the sensing bulb or element is in fact dry. WMO provides a page chapter on the measurement of temperature. The thermodynamic wet-bulb temperature is a thermodynamic property of a mixture of air and water vapor.

The value indicated by a wet-bulb thermometer often provides an adequate approximation of the thermodynamic wet-bulb temperature. The accuracy of a simple wet-bulb thermometer depends on how fast air passes over the bulb and how well the thermometer is shielded from the radiant temperature of its surroundings.

A psychrometer is a device that includes both a dry-bulb and a wet-bulb thermometer. A sling psychrometer requires manual operation to create the airflow over the bulbs, but a powered psychrometer includes a fan for this function. Knowing both the dry-bulb temperature DBT and wet-bulb temperature WBTone can determine the relative humidity RH from the psychrometric chart appropriate to the air pressure.

The saturation temperature of the moisture present in the sample of air, it can also be defined as the temperature at which the vapour changes into liquid condensation. Usually the level at which water vapor changes into liquid marks the base of the cloud in the atmosphere hence called condensation level.

So the temperature value that allows this process condensation to take place is called the 'dew point temperature'. A simplified definition is the temperature at which the water vapour turns into "dew" Chamunoda Zambuko Specific humidity is defined as the mass of water vapor as a proportion of the mass of the moist air sample including both dry air and the water vapor ; it is closely related to humidity ratio and always lower in value.

The mass of water vapor per unit volume of air containing the water vapor. This quantity is also known as the water vapor density. The ratio of the vapor pressure of moisture in the sample to the saturation vapor pressure at the dry bulb temperature of the sample.Humidity is most commonly used in reference to weather or the general climate of a place, especially when the temperature is hot.

The first records of the word humidity come from the s. There are other words for this, like mugginessbut humidity is the most formal and common one. Meteorologists weather scientists measure humidity in a few different ways. Relative humidity is expressed as a percentage—the higher the number, the higher the humidity. Tropical rainforests, for example, have a relative humidity of around 80 percent or higher most of the time. Absolute humidityon the other hand, is the amount of water vapor that is present in a particular volume of air.

People tend to complain about heat and humidity. What are some other forms related to humidity? Humidity is used by both meteorologists and laypeople. Most people find humidity uncomfortable, and people often complain about it.

When Moore was little, the two would spend almost all of August at Disney World, braving the humidity and crowds.Catherine Woods Catherine Woods. We all know those numbers mean hot, but what exactly does that humidity percentage tell us? And why should we care? Below, some facts on humidity, and how it affects our daily lives:. Humidity describes the amount of water vapor or water molecules in the air. Saturate the sponge with half a gallon of water — half of what it is capable of holding — and that relative humidity climbs to 50 percent.

Think of a rise in temperature like an increase in sponge size. A sponge that is half saturated with water is at 50 percent humidity. Now, increase the size of the sponge without adding more water. The relative humidity decreases because the bigger sponge is capable of taking on more moisture, but the same amount of water remains. Soaking a sponge with more water than it can hold would cause it to drip.

humidity meaning in hindi

Rain occurs when the rising air can no longer hold the water droplets that have formed clouds high in the sky. The temperature and atmospheric pressure changes as you ascend into the sky — the air gets colder and thinner.

So percent humidity might not mean rain, but it does mean dew. If you have a dew point temperature of 65, that means that the outside temperature must decrease to 65 degrees before dew, or water, will form on your lawn. And if the temperature outside is 65 and the dew point is 65, then the relative humidity is percent.

Dew point temperature is a good indicator of how comfortable or how uncomfortable you might feel, Sobel said. Humidity comes from water evaporating from lakes and oceans. The highest dew point temperature ever recorded was 95 in Julyin Dhahran, Saudi Arabia. In the US, the midwest and Mississippi have recorded dew point temperatures above For example, Pipestone and St. James, Minnesota reported a humidity reading of 86 in Wind can carry moisture in the air pretty far.

Scientists in this study confirmed what many city dwellers already know — people are better at detecting smells in a humid environment. In heat and high humidity, there are more water molecules in the air to bind and carry odorous particles into our nose. Trash still smells in the winter, but the cold, dry air limits how far the stench can travel.Humidity is a measure of the amount of water vapor in the air.

Relative humidity measures the amount of water in the air in relation to the maximum amount of water vapor moisture. The higher the temperature, the more water vapor the air can hold.

Relative humidity is what your morning weather reporter would refer to. Humidity is a natural part of our atmosphere, it comes from the amount of water vapor in the air. It is an integral part of the water cycle, as water vapor is continuously generated by evaporation and removed by condensation. When the temperature is higher, the air can hold more water vapor, meaning that the warmer the climate, the higher the humidity level can be.

For example, a densely saturated amount of air may contain 0.

Hindi meaning of humidity

Colder air cannot handle as much moisture as warmer air. Consider for example a winters day. On the other hand, warm air can handle more moisture than cooler air. If you cool it down to below That is why air conditioning systems often have a dehumidifier built-in. Without them, your walls in the home would be soaking wet during the summer. Unable to hold any more, it would rain.

Colder climates often have lower humidity levels than warmer climates as colder air holds less moisture than warm air. In winter, humidity levels tend to be typically lower. Whereas in summer, humidity levels will be higher, as air can hold more water vapor at a higher temperature.

Small everyday tasks can affect humidity levels. Cooking, cleaning, dishwashing, breathing, clothes washing, showering, and other indoor processes release moisture into the indoor air, making indoor humidity levels rise. Maintaining healthy humidity levels inside your house is vital.

As explained below, poor humidity levels can have an impact on your health and the house itself. Too much humidity can cause dampness and mold, too little means the air becomes dry and uncomfortable.
