I was looking at a site which described the classic demonstration to illustrate how water pressure increases with depth (shown by punching three holes, one above the other separated by a few centimeters, in a container of water): "The smaller the holes, the greater the rate of flow from the holes."
Is this right? Does not the author mean, "The smaller the holes, the greater the velocity of the water"? (I think of "rate of flow" as being total volume passing a point per unit time, which must remain constant. And presumably these relationships only hold when the flow is laminar and frictional forces are neglected?)
