1. The problem statement, all variables and given/known data The horizontal bottom of a wide vessel with an ideal fluid has a round orifice of radius ##R_1## over which a round closed cylinder is mounted, whose radius ##R_2>R_1##. The clearance between the cylinder and the bottom of vessel is very small, the fluid density is ##\rho##. Find the static pressure of fluid in the clearance as a function of the distance r from the axis of the orifice (and the cylinder), if the height of the fluid is equal to ##h##. 2. Relevant equations 3. The attempt at a solution I think I have to apply the Bernoulli's equation but I need two points to apply the Bernoulli equation. How do I find those points? I understand I should show some more attempt but I really can't get the intuition behind these fluid mechanics problem so I am unable to make any attempt. Any help is appreciated. Thanks!
