I found this meme in a facebook group on engineering concepts:
I selected A (steady and uniform). In selecting A I assumed the width of the river to remain constant along its path and no parameters change with time.
But why steady? Velocity doesn't change with time. It's steady.
But why uniform? We get the same volume across any cross section because width of stream doesn't change.
I think people who selected any other option are confusing laminar with turbulent flow. This has nothing to do with it if you made the correct assumptions.
Is my selection (A) and justification for it correct?
