Flow resistance in a pipe
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. It can be successfully applied to air flow in lung alveoli, or the flow through a drinking straw or through a hypodermic needle. It was experimentally derived independently by Jean Léo… WebFlow in pipes is considered to be laminar if Reynolds number is less than 2320, and turbulent if the Reynolds number is greater than 4000. Between these two values is …

WebResistance to Flow. The resistance to flow represented by a severe constriction in a water pipe is analogous to the resistance to electric current represented by a common electric "resistor".. The severe constriction will have more resistance than the remainder of the pipe system. Likewise a resistor in an electric circuit will generally have much more … WebThe resistance to flow of a fluid and the resistance to the movement of an object through a fluid are usually stated in terms of the viscosity of the fluid. Experimentally, under …
