Maybe you can educate us and let us know what laminar means? thanks
at steady state, tau(shear stress of fluid/gas passes by perpendicular to the cylinder wall) = mu(coeffiecient of friction)*du/dt = 0. du/dt is the change of fluid/gas velocity. At this state, the boundry layer of the fluid reaches uniform flow, hence the term laminar comes into play. Laminar flow will behave like an air foil where the flow on top and bottom of the air foil meet at the end without any turbulent/eddies. That's as far i can remember from fluid mechanic course. I know it can be drived further into energy equation using Bernoulli's equation.
Set,
