This question has been asked two times
Now my question will be different from all those questions, since I will be asking where exactly I am having trouble understanding the working of an atomizer rather than just asking explain the working of atomizer.
While deriving equation of efflux , we take the pressure of liquid to be at the atmospheric pressure i.e $P_2= P_o$
Now when I am applying this logic to an atomizer, I am getting a contradiction :
Now the liquid at the horizontal level below the height is at $P_o$ . Since pressure increases with depth
$P_o>P_1$.
When we look at the horizontal tube in order to liquid to flow $P_3>P_1>\mathbf P_o$ . Now this leads to an absurd result as earlier i have shown $P_o>P_1$ but here $P_1>P_0$
Why the pressure end of horizontal tube is $P_o$?
As it was how we derived it in equation efflux.
My question
Why the pressure at the end of horizontal tube is not $P_0$? I am assuming that assuming that me taking pressure $P_o$ at the end of the horizontal tube is my only mistake . If there is any other mistake please point out freely.
What am I missing here ?
