  2. Operating temperature - Wikipedia

    en.wikipedia.org/wiki/Operating_temperature

    An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...

  3. Mean radiant temperature - Wikipedia

    en.wikipedia.org/wiki/Mean_radiant_temperature

    The concept of mean radiant temperature ( MRT) is used to quantify the exchange of radiant heat between a human and their surrounding environment, with a view to understanding the influence of surface temperatures on personal comfort. Mean radiant temperature has been both qualitatively defined and quantitatively evaluated for both indoor and ...

  4. Room temperature - Wikipedia

    en.wikipedia.org/wiki/Room_temperature

    Retrieved 4 April 2018. 1.2.3.3 Definition of Room Temperature: According to the United States Pharmacopeia National Forumlary [ sic] (USP-NF), the definition of room temperature is between 15 and 30 °C in the United States. However, in the EU, the room temperature is defined as being 15 to 25 °C, while in Japan, it is defined being 1 to 30 °C.

    Simple rapid stirring of a mixture of the amine and di-tert-butyl dicarbonate (Boc 2 O) suspended in water at ambient temperature, an example of an on-water reaction. [11] Heating a mixture of the amine to be protected and di-tert-butyl dicarbonate in tetrahydrofuran (THF) at 40 °C [12]

  6. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    A hot, less-dense lower boundary layer sends plumes of hot material upwards, and cold material from the top moves downwards. Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy ( heat) between physical systems. Heat transfer is classified into various mechanisms ...

  7. Ambient pressure - Wikipedia

    en.wikipedia.org/wiki/Ambient_pressure

    The ambient pressure at sea level is approximately one atmosphere, which is equal to 1.01325 bars (14.6959 psi), which is close enough for bar and atm to be used interchangeably in many applications. In underwater diving the industry convention is to measure ambient pressure in terms of water column. The metric unit is the metre sea water which ...

  8. Wet-bulb globe temperature - Wikipedia

    en.wikipedia.org/wiki/Wet-bulb_globe_temperature

    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). [ 1]

  9. Effects of climate change on human health - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    The projected annual average temperature of above 29 °C for these regions would be outside the "human temperature niche" – a suggested range for climate biologically suitable for humans based on historical data of mean annual temperatures (MAT) – and the most affected regions have little adaptive capacity as of 2020.
