Home Made Aspirator Mathematics

Hi bees, just had to show you this, its all the maths behind making an aspirator!(the bernoulli principle)
the gentleman who appears on this page actually made a tap powered aspirator that crushed a 55 gal drum!!(a force of 13 tons required on the walls of the drum and a drop to about 40% of atmospheric pressure!). Just watch the video if you dont believe

amusing video:

un-amusing mathematics:

bernoulli principle

I never understood why people always refer to it as the bernoulli principle around here.  I've never heard anyone in a classroom environment refer to how an aspirator works as this, but instead they refer to the thermodynamics of a nozzle to explain how it works.  I think I wrote something back in the day about all the equations that were involved, but I don't feel like digging for the search engine for it right now. 

If at first you don't succeed, try, try again. Then give up. There's no use being a fool about it.
