Most of these prop formulas don't seem to work for me. In my experience
it would appear that there is a non-linear load increase in diameter increases.
The above formula yields approximately a 98% ratio, but in my opinion it's
inverted.
<BR>Just be aware that if you increase the diameter, you may find that
the numbers you get by using the formulaes may indicate that you are generating
less of a load, but in actuality you may find the opposite to be true!
