Understand Through Practical What Bernoulli’s Principle Is



Bernoulli’s Principle :
Bernoulli’s Principle which is also known as Bernoulli’s Equation is that principle that tells that a fluid in its ideal state, its pressure and density are inversely related to each other. In other words, when a fluid or liquid moves in slow speed then it puts more pressure than that fluid that moves faster. Here Fluid word applies on all Liquid and Gas. Today we will try to make you understand what Bernoulli’s principle exactly is and how it works. So let us start.  CLICK HERE TO KNOW Make Fire Extinguisher Carbon Dioxide Gas Using Lemon ...
Understand Through Practical What Bernoulli’s Principle Is
Materials Required :
-    1 glass funnel
-    1 small table tennis ping pong ball

Bernoulli’s Principle Experiment :
Number 1 :
Put the ping pong ball in glass funnel first and then take funnel’s lower part near to your mouth. Now keep the funnel straight and blow in it. You will see that ball doesn’t fall out of the funnel but it start rotating inside it. This will surprise everyone.

Number 2 :
This time take the funnel horizontally to your mouth and then again put a ping pong ball in it, again ball fast in it. But still ball is not falling out of the funnel but it will again start rotating in funnel, this will again surprise everyone and they will think why this is happening.

Number 3 :
Make it a bit difficult this time and let the face of funnel downward and then put a ping pong ball in it. Now blow from the other side of the fennel, you will again see that ball is rotating inside the funnel in place of falling outside and third time in a raw everyone will be surprised.

But why this is happening?
Actually its answer is Bernoulli’s Principle, because according to this principle when we blow air in the tube of funnel then that don’t come out of it straight but it runs around the ball and puts pressure on ball from all sides. With that the pressure on the top of the ball will be the highest which will not allow ball to come out and this is Bernoulli’s principle.

In simple words, when you blow in the funnel then the speed of air is fast but when this air comes out of funnel then its speed decreases and this is the reason why the pressure in the funnel tube is not high while the outer part of funnel has more pressure. In this situation, the pressure on ball will move from higher pressure to lower and ball try to enter in funnel tube and when this don’t happen then the ball neither falls outside of funnel not it enters in the funnel, all the ball can do is just start rotating inside the funnel. 

So friends, hope now you understood the Bernoulli’s principle, if not then try this principle at your home, you will have answers of all your question automatically.
