Boundary Layer Thickness for Flat Plate

Engineering Asked on May 28, 2021

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.
