<div>Sounds more realistic. And remember that while the fan is moving that air it is soaking up power. I much prefer my electric fans.</div>

<p class="x_MsoNormal">Listers</p>
<p class="x_MsoNormal">About a month ago I posted to the list looking for a verification of a CFM calculation of the stock 4 blade fan on a 100. </p>
<p class="x_MsoNormal">Bill Atterbury responded that my numbers looked like they were off by a factor of 10. Bill was correct.
</p>
<p class="x_MsoNormal">After revisiting the question it looks like the CFM should be approximately:</p>
<p class="x_MsoNormal">Fan specs: Pitch= 1-1/8 inch </p>
<p class="x_MsoNormal" style="margin-left:.5in; text-indent:.5in">Overall diameter=14.75 inches
</p>
<p class="x_MsoNormal">CFM @ 700 RPM =310 CFM</p>
<p class="x_MsoNormal">CFM @1000 RPM =444 CFM</p>
<p class="x_MsoNormal">CFM @4000 RMP= 1776 CFM</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">So if you wonder why a small 12 inch electric fan that puts out 1250 CFM (FlexALite#111) seems to cool the 100 a lot better at idle</p>
<p class="x_MsoNormal">this may help to explain it, unless of course I have made another mistake.
