How to calculate rate at which a carpet can absorb liquid?a

    1. The problem statement, all variables and given/known data
    I am trying to figure out how to calculate the rate at which a piece of carpet can absorb a liquid such as water or oil. This is for a real life project. I thought that maybe I could use related rates to solve for the rate of volume increase in the carpet if it was rectangular, but I I'm am not really sure if the volume of the carpet even increases when it absorbs a liquid. I want a solid way to calculate this mathematically but I'm not sure if this is the way?

    2. Relevant equations

    3. The attempt at a solution
