Forgive me for asking this 'stupid' question.
[This link Point to another website Only registered and activated users can see links.]
As per the image attached above* which one of the P2 will be bigger? The upper one or lower one?
From my research*
As the flow rate remains constant through a straight pipeline* the velocity will increase when the diameter or size of the pipe / nozzle decrease.
When the velocity of the fluid in a nozzle or pipeline increase* pressure will decrease.
Will a higher velocity fluid produce more force* and then pressure?
Example* when we make a little opening at the pipe outlet* the velocity of the fluid will increase and lead to a stronger force (pressure) as it can travel in a longer way. (Is this correct?)
We will feel the force or pressure if the fluid's velocity increases (such as pain)?
Appreciate if someone can help me by explaining to me. Thank you.
