I did a Civil Engineering course some years ago and from my textbook I had a question on boundary layer thickness. So far I have been able to calculate the transition distance, but I am not sure how to calculate the boundary layer thickness from there. The purpose of this question is to work out how to calculate the boundary layer thickness from what I have said.
Try using the following formulas for boundary layer thickness over a flat plate. These formulas are empirically derived.
For Laminar Boundary Layer
For Turbulent Boundary Layer
