Oil & Fuel Diesel newbie question: windchill

[CobyRupert]

That is irrelevant to a can of fuel. You cool liquids like soup by blowing to cause evaporative cooling. A fuel can wont have liquid on it to evaporate so wind chill is not a factor. Ambient temperature is the same so gelling will occur the same time on both fuel cans as long as all other factors are relevant (sun, amount of fuel, etc)

Ok, evaporative versus radiant cooing, whatever. Both spoons are undergoing evaporative cooling. The one that has wind blowing across it undergoes faster cooling. It is this that is similar to the two fuel cans.

Gelling will occur in the fuel cans at the same temperature, but not at the same time.
The can in the wind reaches that temperature first.

Yes, exactly. I realize that both will gel up, that is clearly understood. But the can outside will do it faster.

My question from my original post:

Which can gels up quicker?

Funny how many people don't realize that if you have a temperature of +1C, and a windchill of -40c, water will not freeze! I would say, it's actually a very poor method of reporting temperature. So, even thought the wind chill is reported to be -40c, my skin won't freeze.

Windchill has no effect

Windchill is an estimate of what the temperature feels like as the wind increases and wicks water vapor away from your skin. To everything that doesn稚 sweat 20 degrees is 20 regardless of wind speed

Wind chill DOES have an effect. Wind affects the rate at which heat is removed from an object - right up until that object reaches the ambient temperature, at which point wind ceases to have an effect.

Where some people get confused about wind chill is in thinking that it makes an object cooler than the ambient temperature. If it's 40˚F out, but the wind chill is 20˚, a bucket of water will not freeze, no matter how hard the wind blows.

The original question was “Which can gels up quicker?” and the stated temperature was 0 degrees. The OP said it was windy but nothing about it being sunny, dark or snowing. Nothing mentioned about how long the cans were sitting but since they have summer blend fuel in them one must assume they have been sitting for months

The fuel in both cans is 0 degrees

Temperature in my uninsulated machine sheds are always warmer than outside despite laving light color steel roofs. During the day they soak heat even if it is cloudy. During the night the heat sink of items stored inside emit enough heat to keep it warmer.

"Nothing is mentioned about how long the cans were sitting..." True, but the question "Which can gels up quicker?" has a built in presumption that the fuel in the cans are initially at an above gel forming temperature. Otherwise they can't "gel up" if they're already gelled up.

And to be a fair comparison, we must assume they are initially at the same "above gelling" temperature.

Asking which one gels up (i.e. cools) "quicker" means we're talking about the rate at which heat is removed, until both are at 0 degrees.
The can in the wind will cool off quicker.
Both will eventually be 0 degrees.

Is the outdoor can sitting on a pallet.....in a field?!!!

Wind chill & the effect of air moveing past an object and removing heat?? Radiator & fan to cool engine coolant. Block the air flow and the coolant becomes warmer!

Diesel fuel and winter treatment? Every area will their own specifications and methods some of which are regulated by standards set.

I change my windchill wipers every Spring, after they Fall off a few times. Summer better than others.
