Homework Statement



With a little effort we can blow across a dime on a table and make it land in a cup, but how can it be explained? I know that is because the bernoulli princle
(qv^2)/2 +qgh + p = const

Homework Equations



but what happens with pressure during this action?

the dime has a cross sectional profile, the side your blowing experiences a pressure equal to the first term in your equation
