Case of Rubber Sheets in Contact with a Liquid

6 Case of Rubber Sheets in Contact with a Liquid 

Three cases appear for a rubber sheet in contact with a liquid  

Let ns remark that in the third case, as gradients of liquid concentrations are developed through the thickness of the rnbber, the rubber sheet becomes heterogeneous, with a gradient of change in the thickness and gradient of change in the diffusivity.
