Or that a flow meter wouldn't tell you how much oil is flowing?

Do ya suppose that the flow rate might have something to do with engineering
the proper solution for stopping (or even STOPPING) the leak, genius?

Do ya suppose that the leak might be nothing like a fire at your house,
genius?

Unless, of course, knowing the physics of the leak might have something
to do with finding the right solution to stopping the leak, genius.
