Can you switch the basis mid-problem when solving unit mass balance equations?

[member 392791]

Hello,

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.
