face=Arial>Hi Ron and list,</FONT></DIV>
<DIV> </DIV>
<DIV>I want to create a graph in Excel that shows how much power required for a
given CDa to reach a specific speed.</DIV>
<DIV> </DIV>
<DIV>To this I need a formulae that I can use in Excel. I have a library
of technical motoring books that puts to shame virtually any public lending
library in the UK and maybe some colleges. However, I can't find the exact
details of what I need.</DIV>
<DIV> </DIV>
<DIV>The Forbes Aird Aerodynamics book includes a formulae along with a value
that I don't see referenced in the text.</DIV>
<DIV> </DIV>
<DIV>The Colin Campbell Sports car book is about the same but with a different
value I don't see referenced in the text, which is:</DIV>
<DIV> </DIV>
<DIV>Drag Horsepower (I'm ignoring non-drag horsepower for now) = Coefficient of
drag x frontal area x mph cubed DIVIDED by 146,000. So what is the
value of 146,000?</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
<DIV> </DIV>
