Test: Boundary Layer Theory - 2 - Question 1

### The maximum thickness of boundary layer in a pipe of radius r is

Detailed Solution for Test: Boundary Layer Theory - 2 - Question 1

The thickness of the boundary layer represented, by 8(greek 'delta’) is arbitrarily defined as that distance from the boundary surface in which the velocity reaches 99% of the velocity of the main stream, in a pipe the free stream velocity is at the centre of the pipe. Therefore maximum thickness of boundary layer is r.
