It is a complex subject; in fact it's probably the most complex of the physical sciences. Even fairly simple physical systems can have very complicated solutions, and some subjects, such as fluid turbulence, are a long way from being well understood. The study of fluid flow is of great importance in fields like chemical engineering and meteorology.

The SI unit of flow rate is (m^3)/s, but other rates can be used, such as L/min. Flow rate and velocity are related by the product of the cross-sectional area of the flow by its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing out of the pipe.

In the transition region (Re between 2000 and 3000), the fluid is unstable and may change back and forth between laminar and turbulent flow.

He was able to characterize the transition between these two types of flow by a parameter called the Reynolds number that depends on the average velocity of the fluid in the pipe, the diameter, and the viscosity of the fluid.
