Component A is diffusing from a point source inside a conical device as shown below: Figure 1: Conical diffusion path The sides of the cone are at a 26.6 degree angle so that the radius of the cone at any distance Z from the origin is equal to 0.5Z. Derive an expression for the mole rate (kmol/s) of component A in terms of Z and XA using the boundary conditions that at Z=Z1,XA=XA1 and at Z=Z2,XA=XA2 . You may assume that NB=0
