Problem #1: A very thick slab of a solid has a uniform concentration of solute A of co= 1.0 x 10-2 kg mol/m². Suddenly, the front face of the slab is exposed to a flowing fluid having a concentration of A of c₁ = 0.1 kg mol/m² and a convective coefficient of k, = 2 x 10-7 m/s. The equilibrium distribution coefficient if K = C₁/C₁ = 0.5 and the diffusivity of A in the solid is DAB = 4 x 10 m²/s. Assuming that the slab is a semi-infinite solid, calculate the concentration of A in the solid at = 0.01 m from the liquid/solid interface at t= 3 x 10¹ s using: (A) mi The equations for the concentration of a solute inside a semi-infinite medium undergoing unsteady state diffusion; and m

Problem #1: A very thick slab of a solid has a uniform concentration of solute A of co= 1.0 x 10-2 kg mol/m². Suddenly, the front face of the slab is exposed to a flowing fluid having a concentration of A of c₁ = 0.1 kg mol/m² and a convective coefficient of k = 2 x 10-7 m/s. The equilibrium distribution coefficient if K = c/c = 0.5 and the diffusivity of A in the solid is DAB = 4 x 10" m²/s. Assuming that the slab is a semi-infinite solid, calculate the concentration of A in the solid at a 0.01 m from the liquid/solid interface at t 3 x 10 s using: H (A) (n The equations for the concentration of a solute inside a semi-infinite medium undergoing unsteady state diffusion; and mi
