Having designed and tested fan cooling for my company's central
office equipment (think telephone & internet), I know that 20
watts will barely get me to the neighborhood of 200 feet per minute
in a small portion of a guided box. And that's quite a wind. I
can't imagine a ceiling fan getting anywhere close to 200 feet per
minute.<br>
Also I would point out that the sensible cooling effect of a
wind/breeze is a very strong function of the humidity - just ask all
those folk who weathered the recent heat waves how much a wind
helped when the humidity was upwards from 90%.<br>

honing in on that last bit regarding the fan moving at 200 mph
over a body, what is the speed of a ceiling fan--at the low,
middle and high speed? Just curious.<br>
<br>
We use fans a whole lot in our open high ceiling house, both
in the summer and in the winter. In the latter case, the
ceiling fans seem to help distribute heat from a stove
source. Last year when there was some discussion on this list
about the efficacy of this method of distribution, I tried
unsuccessfully to measure the effects. Surely the greater
warmth I feel down below is not my imagination?<br>
<br>
Thanks, Sacie<br>

A fan, using say 20 Watts blowing air at 200 feet per
