Hi, I went for a job interview and testing. One question is bothering me as to the reasoning. here is the question - if you answer could you please respond with the reasoning/physics. ty I'm assuming all tanks/vaccum and pipe sizes to be equal as no info was provided. Tank "A" draws off the top down into Tank "B" into the top. Tank "C" draws off the top down into Tank "D" into the top. The difference is Tank "C" and Tank "D" are much further apart then Tanks A and B. Both are a straight verticle drop. At first I thought of head pressure being the difference but if they are drawing out of the top of the higher tank then doesn't the vaccum determine the rate - regardless of the drop ? The answers I had to choose from was- which empties faster, Tank A (into B) or Tank C into D or the same. Thanks
