Question

A flat plate of 6m length and lm wide is kept parallel to a uniform stram of air of velocity 20 m/s. The boundary layer changes from laminar to turbulent at a Reynolds number $5 \times 10^5$. Find the extent of the laminar boundary layer on the plate (i boundary layer thickness at the edge of the laminar boundary layer. ii boundary layer thickness at the trailing edge of the plate. The kinematic viscosity and density of air are $1.5 \times 10^{-5} m^2/s$ and $1.23 kg/m^3$ respectively.
