A uniform air stream with velocity U = 10m/s flows over a flat plate of length 10 meters in the first meter the boundary layer is laminar but beyond this point boundary layer is fully turbulent Assume that the pressure gradient zero and the plate width is one meter the temperature of the plate is 100⁰ C and the temperature at infinity is 20⁰ C.

Compute

A. the momentum boundary thickness one meter from the leading edge and at the end of plate.

B the total drag force on the plate (On eside)

C. The thermal boundary thickness one meter from the leading edge and at the end of the plate

D. the average heat flux from the plate.
