Switching a basis mid problem

  1. Sep 26, 2013 #1

    I was wondering if it is allowed when doing problems on multiple unit mass balances to switch the basis made at the beginning of the problem and apply it to a new control volume, while keeping the old basis for previous control volumes?

    Thank you

    Yes but might be tricky. You'd have to find an equivalence ratio between old & new basis.
