Flow and Dissolution in Porous Media

The stoichiometric coefficient, times the moles of acid consumed in the pore in a time At is equal to the moles of material dissolved  

The relationship between the inlet and outlet concentrations to the pore is analogous to Equation (11-61)  

We now combine Equations (11-90) and (11-91) with a mole balance on the acid to obtain the pore radius as a function of time. 

Application of the mole balance to a specific pore in the network gives the radius of the pore as a function of time in increments of At
