A friend came over and we had a discussion about pipes in the cold. When
it's say, 30 degrees with a wind chill of say ... 25, would materials
(pipes, ducts, etc) that's in the wind be considered at 30 or 25?
I know what you're thinking - what's a pipe doing exposed to wind? But
that's a given in the situation, and not really a matter to discuss. The
question is basically, do non animate object get effected by the wind or
does is only apply to people, dogs, and other animals?
--------------------
They most certainly do. A couple winters ago, I had my water valve to my
downstairs toilet freeze and leak. This is in a small, unheated room in my
house with a crawl space of about 2 1/2 to 3 feet underneath. The wind was
coming in the cracks around the access doors to the crawl space. Combined
with the frigid temperatures (below 0°F), this brought the temperature down
enough to freeze that valve. While waiting for the plumber (who was dealing
with an unprecedented amount of frozen pipes) the water in the toilet also
froze. Fortunately, it didn't crack the bowl, but it did mean a couple days
with a space heater to thaw everything after the valve and a portion of the
feed pipe was replaced. I've never had that freeze before, even with the
temperature outside down to -30°F, but no wind. Even the plumber said it
was the wind chill which was freezing the pipes.
