Until Lemmy actually generates unique OC and this community doesn’t sit idle with no submissions, it’s probably ok.
What’s the difference between wet bulb temperature and regular temperature?
Per wikipedia: The wet-bulb temperature is the temperature read by a thermometer covered in water-soaked cloth over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature; at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling.
Living organisms can survive only within a certain temperature range. When the ambient temperature is excessive, many animals cool themselves to below ambient temperature by evaporative cooling (sweat in humans and horses, saliva and water in dogs and other mammals); this helps to prevent potentially fatal hyperthermia due to heat stress. The effectiveness of evaporative cooling depends upon humidity; wet-bulb temperature, or more complex calculated quantities such as wet-bulb globe temperature (WBGT) which also takes account of solar radiation, give a useful indication of the degree of heat stress, and are used by several agencies as the basis for heat stress prevention guidelines.
A sustained wet-bulb temperature exceeding 35 °C (95 °F) is likely to be fatal even to fit and healthy people, unclothed in the shade next to a fan; at this temperature human bodies switch from shedding heat to the environment, to gaining heat from it.[9] In practice, such ideal conditions for humans to cool themselves will not always exist – hence the high fatality levels in the 2003 European and 2010 Russian heat waves, which saw wet-bulb temperatures no greater than 28 °C.
Wet bulb is when you take a thermometer and pour water over it then lightly blow air onto it then reading the temperature.
It simulates cooling through evaporation and this post basically means you could drench yourself in water and still die from the heat.
it combines humidity with temperature, too high and your sweat does not evaporate and your body gains heat from the environment instead of shedding heating into the environment
Anyone read Ministry For the Future?
Just started it yesterday! The opening chapter feels like what the South might suffer if the wet bulb temperature went up a few degrees higher.
