![]() Therefore, convection is negligible compared with diffusion. (b) The distance between capillaries is 10-4 m oxygen needs to travel half of this distance, which yields a value of PE equal to 0.0455. Assume that convection is the same as diffusion, i.e., Pe = 1, L is 0.123 cm. The relative importance of convection and diffusion is evaluated by Peclet number, vL (S1.1.1) Pe = Dij (a) Solving for L, L = PeDij/v.
