Bernoulli's Theorem

Floating of Ping-Pong Ball on  water jet& air jet

The principal  behind floating of a ping -pong ball is based on  BERNOULLI'S THEOREM

now i am  going to tell you the whole principal behind this phenomenon.

First to understand this phenomenon, we should to look upon BERNOULLI'S THEOREM

BERNOULLI'S THEOREM

       This theorem is like energy conservation principle.

  "When a non-compressible and non-viscous Liquid or Gas flow like linear current motion, then  at any point of it's path the TOTAL ENERGY (sum of pressure energy, kinetic energy and potential energy) of liquid or gas  remains constant."

                                     It is the BERNOULLI'S THEOREM

now the the conclusion comes out that

           "the side where the velocity is more, the pressure will be less 

             & where velocity is less the pressure will be more"

using this principle we can easily understand the myth behind ping- pong ball 

floatation............................................

 since the air is  coming out with high speed  from drier machine, hence the pressure becomes low around the ball and therefore the outer pressure push the ping pong ball into the air jet,therefore 
ball  does not come  out to the air jet.This process goes on untill the the air jet is not stopped.

 now we have understood the phenomenon behind the ping-pong ball.
