WebHagen–Poiseuille equation. In nonideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section. 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 …

WebSuppose for an orifice-type differential flow meter, the DP range is 0 mmH 2 O to 2000 mmH 2 O. The output flow range is 0 m 3 /hr to 1000 m 3 /hr. Step 1: Calculate mA corresponding to 800 mmH2O.
