The answer is both of them. At 0F, it's cold enough to freeze

pipes. And depending on where the pipes are, they can be

affected by the windchill. Again, just two examples:



Affected how? The wind may make then freeze a bit faster by removing

heat faster, but regardless of the wind chill number, the pipes will

never see anything below 0 degrees.



It would help if you didn't edit out the pertinent part you're responding
to and would at least answer the simple questions posed.
I gave you two examples:

"The answer is both of them. At 0F, it's cold enough to freeze
pipes. And depending on where the pipes are, they can be
affected by the windchill. Again, just two examples:

A - Pipes are in a cabin with no heat. Do you think the cabin
inside temp will be the same overnight as the temp drops without
regard to what the windchill is? If the reported windchill was
large, would you not agree that the pipes are going to be
more likely to freeze?

B - Pipes in a drafty crawlspace. "


The temps that the crawlspace reaches on a cold night is
affected by the windchill. So is the temperature that an
unheated cabin will reach inside. With significant windchill
they could reach temps overnight that they would not reach
without windchill. It's that simple.

No. If the temperature is 35 and the wind chill is 25, the pipes will

not freeze. They will never go below 35F



Why do you persist in only looking at the case where the outside
temp is well above zero? Good grief. The question and context
that started all this, again, was where the temp was ZERO and
there was an additional 10 deg of winchill.













Then why won't Gordon just admit he's wrong, even after his

own reference from NOAA says that inanimate objects can be affected

by windchill?





Best to ask Gordon.



I thought maybe you'd have an answer, because you seem just
as confused and unwilling to accept the fact that windchill does
affect inanimate objects. Like him, you're stuck in a loop:

It has no effect, it doesn't matter, it can have nothing to do
with pipes freezing. But then you say the only effect windchill
has is to cool off inanimate objects faster.










No matter how you term things, it does not change the laws of physics. .



Again, tell that to Gordon. He's the one that said windchill had

absolutely no effect on inanimate objects and won't just admit that

he's wrong. Apparently you agree he's wrong too.



Gets back to definitions. Wind can move heat away faster but inanimate

objects will never feel the "chill" number, only the actual number.

No one said they can feel the number. Only that they can be
affected by it too. Again, the drafty crawlspace, the unheated
cabin.




They may get there a bit faster though.

It's not just a question of a bit faster. Again, on a night where
the outside temp drops to 20F and the windchill is 0F, do you think
the lowest temp of an unheated cabin is going to be the same as it
is if the windchill was reported as 20F? That is a very realistic
example where it makes a difference.




NOAA confused things with their

definition. .



I don't see a problem with their definition. They did contradict
themselves in answering the question. But even they say windchill
affect pipess.
