You can say grade school as much as you like, but it doesn't change the fact that Smith didn't even know the maximum rate of the pumps.
Oh, he got it right. It is written right on the face plate. Plus I happen to know the actual flow rate was much lower than the flow meter indicated.
You may imagine you know differently based on some manual you dug up, but trust me: the face plate is right, whatever manual you found is wrong. I know how manuals get written. It is like making sausage; you don't want to know.
