The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
A wash of diluted ink or watercolor paint applied in combination with drawing is called pen and wash, wash drawing, or ink and wash. [ citation needed ] Normally only one or two colours of wash are used; if more colours are used the result is likely to be classified as a full watercolor painting .
The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

What wet bulb globe temperature tells you about the weather In hot temperatures, the human body typically creates sweat as a way to control body temperature through evaporative cooling.
‘Wet-bulb temperature’ refers to temperatures taken with a thermometer covered in a wet cloth, which are normally slightly cooler than ‘dry-bulb’ temperatures.
Wet bulb globe temperature is a better indicator of the risk posed by outdoor conditions than either heat index or temperature, experts say.
A handheld wet-bulb globe temperature meter, including a black-globe thermometer (left). The MRT can be estimated using a black-globe thermometer.The black-globe thermometer consists of a black globe in the center of which is placed a temperature sensor such as the bulb of a mercury thermometer, a thermocouple or a resistance probe.
A wet-bulb measurement is taken by covering a thermometer with a water-soaked cloth. The process of the water evaporating from the cloth, thus lowering the temperature, mirrors how the human body ...
