A large plate is at rest in water at 15C. The plate is suddenly translated parallel to itself, at 1.5 m/s. The resulting fluid movement is not exactly like that in a b.l. because the velocity profile builds up uniformly, all over, instead of from an edge. The governing transient momentum equation, Du/Dt = v(d2u/dy2), takes the form
Determine u at 0.015 m from the plate for t = 1, 10, and 1000 s.
