WebTracer transport in laminar and turbulent flow. The straight, parallel black lines are streamlines, which are everywhere parallel to the mean flow. In laminar flow the fluid particles follow the streamlines exactly, as shown by the linear dye trace in the laminar region. In turbulent flow eddies of many sizes are superimposed onto the mean flow ... WebEquation. In standard fluid-kinetics notation: = = where: Δp is the pressure difference between the two ends,; L is the length of pipe,; μ is the dynamic viscosity,; Q is the volumetric flow rate,; R is the pipe radius,; A is the cross sectional area of pipe.; The equation does not hold close to the pipe entrance.: 3 The equation fails in the limit of …
