Orifice head loss equation

An 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 flow reaches its point of maximum convergence, the vena contracta (see drawing to the right) where the velocity reache… WitrynaThere is no friction or losses The velocities at sections (1) and (2) are uniform, i.e, they do not vary in a radial direction. The pipe is horizontal, i.e., z is the same at (1) and …
