Chilly Diesel Problems

The reason there is a Wind Chill factor is the wind will carry away the extra BTU's that still air can not. The body's response is that it tries to get to the ambient temperature faster. At the same speed as if the air was xx degrees colder. The Wind Chill factor. Same reason that RCE stated that turbulent flow will transfer more heat. Laminar flow will have a small slow speed component of air right next to the surface. That small bit of air will insulate the surface from the air above. Works with beer cans also. Same reason that a car radiator works with air flowing over it. No fan and hot day and sitting still and you overheat. I agree with everything you posted, including tissue or beer cans, except the effect is not "wind chill". In moving air the tissue and beer can, if warmer or colder than the ambient temperature will cool or warm faster to the ambient temperature than in still air. Wind chill is the apparent lower temperature (than ambient) that living tissue experiences due to it's inability to keep up with the increased heat loss in windy conditions. It is equal to that temperature the tissue would be exposed to if there was no wind. And with that, I am done with this wind chill discussion. It's leaving me cold. Well, I'm glad to see everybody having fun today. :) |
