A low Reynolds number indicates smooth, laminar flow. wow well explained with experiments !! If we multiply (mass*distance)/time*distance3 and areas fundamental dimensions then length cancels out and we get mass/time which is not right but if we multiply by volumes fundamental dimension we get mass*distance/time2. Three timers were used to time the objects travel, then the three times were averaged. In this lecture, I will derive the partial differential equations, known as Euler and Navier-Stokes equation, that are widely used to model the dynamics of a fluid. Handbook of Mathematical Fluid Dynamics - Google Books . Examples of this include the separation of the atmospheric flow into its average along latitudes and perturbations, the separation of oceanic flow into a slow time . Fluid flow arises in a variety of settings ranging from astrophysics to atmosphere to granular flows to living organisms big and small. However, in practice, specialized topics such as hydrodynamic stability and magnetohydrodynamics use the "hydro-" prefix even when they are applying those concepts to the motion of gases. For the first part of our math problems, we looked at something called Bernoullis Principle.
