The temperature at which air becomes saturated and produces dew.

dew point

or

dewpoint

n
(Physical Geography) the temperature at which water vapour in the air becomes saturated and water droplets begin to form

dew′ point`


n.
the temperature to which air must be cooled, at a given pressure and water-vapor content, for it to reach saturation; temperature at which dew begins to form.
[1825–35]

dew point

The temperature at which air becomes saturated with water vapor and dew forms. The dew point varies depending on how much water vapor is in the air.

dew point

The point at which air saturated with water vapor produces condensation which forms dew.

The principle of operation of a hot-air dryer is simple: Hot air will absorb and hold more water than cool air; for example, ambient air at 75 F with a dewpoint temperature of 60 F has a relative humidity of 59.
The relationship between the wet-bulb temperature, the dry-bulb temperature, and the dewpoint temperature is nonlinear.
It forms when humid air cools sufficiently for water vapor to saturate and produce condensation--the dewpoint temperature.
The Elcometer 319 Dewpoint Meter measures relative humidity (rh), air temperature (Ta), surface temperature (Ts) and calculates the dewpoint temperature (Td) and the difference between the surface temperature and the dewpoint temperature M.
If the coil surface temperature is greater than the dewpoint temperature, then the dry analysis is appropriate.
The chilled mirror measures hydrocarbon dewpoint temperature at line pressure only.
This can be implemented by maintaining the temperature of the controlled space air at a constant value above the outdoor air's morning minimum temperature (Method 1), maintaining the temperature of the controlled space air at a constant value above the air's dewpoint temperature (Method 2), or adjusting the temperature of the controlled space air according to a preset RH (Method 3).
In removing moisture from the air, Munters calculate, then control the dewpoint temperature required.
The bags absorb 280 percent of their weight in moisture at 90 percent relative humidity at 77 degrees F, keeping the dewpoint temperature below the actual temperature, even with day-night fluctuations.
For 1 May-30 September, for each year from 1980 to 1996, Environment Canada provided hourly values of air temperature and dewpoint temperature from the weather station at the Toronto Pearson International Airport in Etobicoke, which is located approximately 15 km from downtown Toronto.
The Humiscan[R] uses a high-quality capacitive relative humidity sensor, a solid state temperature sensor, and a microprocessor to calculate dewpoint temperature, absolute humidity, mixing ratio, and wet bulb temperature.
