Navier-Stokes. Viscosity. A static fluid cannot support a shear. A moving fluid with viscosity can have shear. Dynamic viscosity m Kinematic viscosity n. F. v x. y. Pipe. Steady flow in a pipe involves viscosity. The forces must be balanced. z. a. l.
Constants a, b include viscosity
An incompressible fluid has no velocity divergence.Stress and Strain
Force from gravity
Apply to Navier-Stokes
The result is Bernoulli’s equation.Bernoulli Rederived
