Answer to Question #302561 in Chemical Engineering for SAVARA RAVITEJA

Question

In the Danckwerts model, it is assumed that elements of the surface have an age

distribution ranging from zero to infinity. Obtain the age distribution function for this model

and apply it to obtain the average mass transfer coefficient at the surface, given that from the

penetration theory the mass transfer coefficient for the surface of age θ is

/( ) DAB
