When the ratio of forces, given by the Reynolds number, is low, this law gives the value of the friction factor used in the Darcy- Weisbach equation.
This law is utilized in the Wissenberg-Rabinowitsch equation as a Newtonian constitutive equation. Wilberforce extended its application to situations where the ratio of (*) inertial forces to viscous forces exceeds a critical value. When the ratio of forces, given by the Reynolds number, is low, this law gives the value of the friction factor used in the Darcy- Weisbach equation. It can be derived from the Navier-Stokes equations and assumes that the flow is essentially laminar along the axis and zero in the radial direction. For 10 points, name this law of fluid mechanics which is used to characterize laminar flow through a tube with a constant circular cross section, such as the flow of blood through a capillary.
