ANSI Pump Sizes vs HP ?

Wondering if anyone has worked a lot with ANSI pumps. I'm trying to find a standardized list of nozzle sizes vs pump HP. For example an 8 X 10 Pump with 40 HP.

Good luck. If you find one, post it here. But don't waste a lot of time looking - think how many productive man-years were spent searching for the Holy Grail and a Philosopher's Stone.
