Question

For steady fully developed, incompressible, laminar flow of newtonian fluids with constant properties between two stationary parallel plates, the ratio of average velocity to maximum velocity is

Answer 1

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.
