prop formula

[George Kennie]

One last entry regarding the prop formula.Some of us more curious
types have been overheating our calculators on this one and what
I've discovered is that Ken Blackwell probably had the most
difinitive approach. No matter what you use as a formula, in some
ranges the formula will not work.It would appear that when you
consider the overall power application the formula would need to be
a randomly revolving equation applied as the need dictates. As Ken
says, you need to get real and try what works in the real world.
