1. The problem statement, all variables and given/known data I am just a little bit confused. I have a question that is asking me to explain what the physical significance of volumetric flux is. 2. Relevant equations I am not sure that this problem requires any equations! 3. The attempt at a solution I know that the flux corresponds to the rate of volume flow through an area, but I feel like that can't be the answer.. It just seems to common sense to be the answer.
