Apple slices mm thick are exposed to sulphur fumes from top in asulphuring house before drying. If the Biot number for mass transfer is higher than and the surface concentration of SO is mol SOm determine how long it will takefor the concentration on the nonexposed surface of the apple slice to increase by of the initial concentration difference using both the analytical solution and Heislercharts. Assume zero initial concentration of SO in the apple, negligible mass transferthrough the sides of the apples, and a diffusion coefficient of SO in the apple of xms
