It has a lot of information.
If you are looking for comprehensive information / explanations / definitions etc. ref. pump performance curves (Head - Flow, Efficiency, BHP, NPSH etc.) this is not all that easy to find.
Careful with calculations involving Affinity Laws (pumps at diff. speeds, reduction of impeller dia. etc.), useful but you need to be aware of what they really mean (e.g. Q, Speed -rpm-, Power not independent variables. Affinity Laws are simply eqn.s of Iso-efficiency curves. Understanding that, they are useful for many calcs.).
