    2. Relevant equations

    ordinary mass balance


    3. The attempt at a solution

    So far I have gotten:
    d[rhob*V]/dt = Min - ?????

    d[rhob*V]/dt = Min - rhob*Min*(1-n)/(rhos + rhow)

    is what i got

    Mind me asking how you got the out term (the rhob*Min*(1-n)/(rhos + rhow))? Not saying that you are wrong but having trouble getting this and curious how you got to that.
