6.13 Fluid at a uniform speed U flows into a channel between two parallel plates a distance d apart. A laminar boundary layer grows on each plate. (a) At approximately what distance from the inlet will the two boundary layers first touch? (b) If the flow remains laminar, qualitatively sketch the velocity distribution between the plates a long distance after the boundary layers meet, noting that the mass flow rate is constant along the channel. [(a) x/d = 0.01 (Ud/v).]
