Fluid flow momentum equation
WebThus for laminar flow of a Newtonian fluid in a pipe the momentum flow rate is greater by a factor of 4/3 than it would be if the same fluid with the same mass flow rate had a uniform velocity. This difference is analogous to the different values of α in Bernoulli's equation ( equation 1.14 ). WebThe Navier–Stokes momentum equation can be mathematically deduced as a distinct type of the Cauchy momentum equation. The general convective structure is ... the Navier-Stokes equations are partial differential equations that express the flow of viscous fluids. These equations are generalisations of the equations developed by Leonhard Euler ...
