wet-bulb temperature

At a wet-bulb temperature of 88 to 90 degrees, called heat condition red, heavy work is restricted to six hours a day.

The surface of a warm, damp body takes up the wet-bulb temperature of the air around it.

A higher difference between the dry-bulb and wet-bulb temperatures indicates a lower relative humidity.

Wet-bulb temperature: The temperature difference between the head and body depends on the relative humidity of the air.

What snow-making operators look at is the wet-bulb temperature, which is adjusted for humidity.

At some point the water vapour in the air becomes saturated (and has cooled to the thermodynamic wet-bulb temperature).

Under Defense Department rules, work shifts must be significantly curtailed when the wet-bulb temperature passes 88 degrees.

Cooling towers are structures for cooling water or other heat transfer media to near-ambient wet-bulb temperature.

It is the thermodynamic wet-bulb temperature that is plotted on a psychrometric chart.

Wind may secure this equilibrium faster, but no wind, however strong, can reduce the temperature of a body below its own wet-bulb temperature.

This is due to heat rejection at or near the air's wet-bulb temperature rather than the higher, sometimes much higher, dry-bulb temperature.

The wet-bulb depression is the difference between the dry-bulb temperature and the wet-bulb 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.

An actual wet-bulb thermometer indicates a temperature close to the true (thermodynamic) wet-bulb temperature.

Cooling of the human body through perspiration is inhibited as the wet-bulb temperature (and absolute humidity) of the surrounding air increases in summer.

In practice the value reported by a wet-bulb thermometer differs slightly from the thermodynamic wet-bulb temperature because:

If there is 100% humidity, dry-bulb and wet-bulb temperatures are identical, making the wet-bulb depression equal to zero in such conditions.

Lower wet-bulb temperatures that correspond with drier air in summer can translate to energy savings in air-conditioned buildings due to:

An actual wet-bulb thermometer reads a slightly different temperature than the thermodynamic wet-bulb temperature, but they are very close in value.

Experimentally, the wet-bulb thermometer reads closest to the thermodynamic wet-bulb temperature if:

At any given ambient temperature, less relative humidity results in a greater difference between the dry-bulb and wet-bulb temperatures; the wet-bulb is colder.

The wet-bulb temperature is essentially the lowest temperature which can be attained by evaporative cooling at a given temperature and humidity.

Water-cooled chillers are normally more energy efficient than air-cooled chillers due to heat rejection to tower water at or near wet-bulb temperatures.

Wet-bulb temperature is largely determined by both actual air temperature (dry-bulb temperature) and humidity, the amount of moisture in the air.
