zasto onda imas one velike ventilatore doma po ljeti da te hlade? :confused: oni rade na istom principu, raspiruju zrak, a hladnije ti je kad puse u tebe...logike li...uostalom, stavi ruku ispred ventilatora, pa ces osjetiti da je nesto hladniji zrak od onog "prije" ventilatora, tj. onog koji uvlaci...

Wind chill is the apparent temperature felt on exposed skin due to the combination of air temperature and wind speed. Except at higher temperatures, where wind chill is considered less important, the wind chill temperature (often incorrectly called the "wind chill factor") is always lower than the air temperature, because any wind increases the rate at which moisture evaporates from the skin and carries heat away from the body. The phase change of water (in sweat) from liquid to vapor requires that the molecules reach a higher energy state
