WebAn orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the … WebAn appreciation of molecular flow principles will be gained by considering in detail the effusion of gas through a small orifice in a thin wall connecting two large vessels A and B. If the mean free path of the gas is 10 or more times the maximum orifice dimension, the passage of molecules through the orifice will produce no appreciable effect ...

For laminar flow in a tube, Poiseuille’s law for resistance states that R = 8ηl πr4. Poiseuille’s law for flow in a tube is Q = (P2 − P1)πr4 8ηl. The pressure drop caused by flow and resistance is given by P2 − P1 = RQ.
