In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers. [1] Responsibility Peter Bradshaw, Tuncer Cebeci, James H. Whitelaw.

As indicated by McDonald (Bertram 1969) integral calculation methods (solving ordinary differential equations for integral parameters) usually depend on the transformation of an incompressible-flow method, and stand or fall with the transformation. In turbulent flow the flow rate is proportional to the square root of the pressure gradient, as opposed to its direct proportionality to pressure gradient in laminar flow. Using the definition of the Reynolds number we can see that a large diameter with rapid flow, where the density of the blood is high, tends towards turbulence.
