Q2 DIFFUSION FROM A CYLINDER A wet cylinder of ager gel at 300 K contains a uniform concentration of urea of 85 mol/m². If the cylinder diameter and length are of 3.0 cm and 3.2 cm, respectively. The diffusivity of urea in the solid is 8x10-10 m²/s. If the cylinder is suddenly immersed in a large amount of turbulent pure water. What is the concentration at the midpoint of the cylinder after 40 h for the following cases: a) The diffusion occurs only in the radial direction. b) The diffusion occurs in radial and axial directions, c) Redo part b if the tube length is 1.0 m.
