The discussion centers on the application of Bernoulli's principle to explain the phenomenon of blowing a dime across a table into a cup. The equation used, (qv²)/2 + qgh + p = const, illustrates the relationship between velocity, pressure, and height in fluid dynamics. The pressure experienced on the side of the dime being blown is directly related to the first term of the equation, emphasizing the role of airflow in creating a pressure differential that moves the dime. Understanding this principle is crucial for analyzing fluid behavior in various applications.

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

but what happens with pressure during this action?
