What is a dry-bulb thermometer?
dry-bulb thermometer A thermometer that registers normal air temperature. It may be used in conjunction with a wet-bulb thermometer: the relative humidity can be found by measuring the depression of temperature registered by the wet bulb. See also hygrometer and psychrometer.
How does a dry-bulb thermometer work?
Dry Bulb Temperature – T It is called “Dry Bulb” because the air temperature is indicated by a thermometer not affected by the moisture of the air. Dry-bulb temperature – Tdb, can be measured using a normal thermometer freely exposed to the air but shielded from radiation and moisture.
How do you take dry bulb temperature?
Dry Bulb Temperature – T. db It is called “Dry Bulb” because the air temperature is indicated by a thermometer not affected by the moisture of the air. Dry-bulb temperature – Tdb, can be measured using a normal thermometer freely exposed to the air but shielded from radiation and moisture.
How is DBT and WBT measured?
The DBT and WBT of the air are measured by a special thermometer called Sling thermometer. It comprises of two ordinary thermometers, but one of them is covered with the wet wick or cloth. The uncovered thermometer measures dry bulb temperature, while the one covered with wet cloth measures wet bulb temeprature.
What is another name for the dry bulb temperature?
The dry-bulb temperature (DBT) is the temperature of air measured by a thermometer freely exposed to the air, but shielded from radiation and moisture. DBT is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature.
Why is dry bulb temperature important?
The Dry Bulb, Wet Bulb and Dew Point temperatures are important to determine the state of humid air. The knowledge of only two of these values is enough to determine the state – including the content of water vapor and the sensible and latent energy (enthalpy).
Is Dry Bulb the same as temperature?
When people refer to the temperature of the air, they are normally referring to its dry bulb temperature. The Dry Bulb Temperature refers basically to the ambient air temperature. It is called “Dry Bulb” because the air temperature is indicated by a thermometer not affected by the moisture of the air.
What is the difference between DBT and WBT called *?
The difference between dry bulb temperature and wet bulb temperature is called wet bulb depression.
What is the difference between dry bulb temperature and wet bulb temperature?
The dry bulb temperature is the ambient air temperature that is measured by regular thermometers, while the wet bulb temperature is measured by thermometers that are wrapped in wetted wicks. The greater the wet bulb depression, the greater the felt effect is on the discharge air temperature.
