*****************************************************************************

I'm sure there are folks out there that have already taken a stab at  
this, but didn't find anything in the archives:

I'm interested in making some bernoulli blowers of different sizes.   
Rather than spend a fortune on different blowers (surplus) and  
different balls, I'm looking for some way to mathematically narrow  
the field down.

For instance, if I know the weight of the ball and the diameter, is  
there an easy (reasonably) way to get in the ballpark with regard to  
air delivery, size of the air column, amount of lift, etc......?  Or  
am I just walking down a primrose path?
