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.
An irreversible process increases the total entropy of the system and its surroundings. The second law of thermodynamics can be used to determine whether a hypothetical process is reversible or not. Intuitively, a process is reversible if there is no dissipation. For example, Joule expansion is irreversible because initially the system is not ...
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 ...
Apparent temperature, also known as " feels like ", [ 1][ 2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature. Apparent temperature was invented by Robert Steadman [ 3] who published a ...
Despite two of its cities – Phoenix and Tempe – passing maximum indoor temperature laws, the county registered 156 indoor heat-related deaths last year, a five-fold increase over the last decade.
Hence, a comfortable temperature in a heated building may be 18 - 22 degrees Celsius (64.4 - 71.6 degrees Fahrenheit). [ 6 ] [ 7 ] Humans produce an obligatory 100 W (0.13 hp) of heat energy at rest as a by-product from basic processes like pumping blood, digesting, breathing, biochemical synthesis and catabolism etc.
Radiative cooling. In the study of heat transfer, radiative cooling[ 1][ 2] is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation .
Hydrometeorology is a branch of meteorology and hydrology that studies the transfer of water and energy between the land surface and the lower atmosphere for academic research, commercial gain or operational forecasting purposes. Whilst traditionally meteorologists and hydrologists sit within separate organisations, hydrometeorlogists may work ...
