What is Psychrometrics? Psychrometrics Theory And Practice Book PDF

The measurement of heat and water vapor in air samples is called psychrometrics. It is used in the refrigerating industry, in designing clean rooms, specific manufacturing processes and other theoretical applications. The branch of thermodynamics called psychrometry deals with terms such as dry-bulb temperature and wet-bulb temperatures, specific heat and relative humidity. A good understanding of psychrometrics theory and practice book pdf will allow you to control the humidity in contained environments. The relationship between wet-bulb temperatures, dry-bulb temperatures, and relative humidity is a crucial concept in psychometry.

Psychrometrics: theory and practice uses the well-understood relationship between humidity and temperature in order to solve practical problems. Dry-bulb temperature is the temperature measured using a thermometer. A device called a thermometer is used to measure wet-bulb temperature. It measures temperature using the cooling properties of evaporating waters.

A thermometer is a traditional thermometer that provides dry-bulb information for psychrometrics. 

Two thermometers make up a hygrometer. One is attached to a wick that has been soaked in distilled water, and the other is left unattached. Two thermometers are spun through the air using a hand-operated spinning machine. The movement lowers the temperature of the wet bulb thermometer through the air. The difference between the thermometer measurements determines the wet-bulb temperature. Because of the nature of psychrometrics, it is possible to use any combination of the three values — dry-bulb temp, wet-bulb temp, and relative humidity — to calculate the last. 

For measuring humidity in wet environments, hygrometers can be used. 

The relative humidity is the amount of humidity that a space has at the moment in relation to its maximum humidity before it becomes saturated with water vapour. A space that is saturated with water vapour will reach its dew point. This is the point where water vapor begins to condense into water. The relative humidity is a measure of how similar the wet-bulb temperature is to the dry-bulb temperature. The temperature of the wet bulb will not drop if there is no water vapor when the hygrometer spins due to supersaturated air. Absolute humidity, on the other hand, is the measurement of the actual density of water vapor in an air sample. These devices are often used in industrial areas, greenhouses, saunas, humidors, and museums.
