Fluid flow is a very broad and complicated topic because of the many different aspects and types of applications.
In this text we will cover the range between these two extremes: when viscosi.
I may at some point cover creeping flow, which occurs when the viscosity dominates momentum or the velocities are very small.
I have covered inviscid flow, which occurs when the viscosity is negligible or the velocities are very large, in two previous texts: Differential Equations and Numerical Calculus.
