Steve Leyton -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bill Brooks Sent: Wednesday, May 09, 2012 9:11 AM To: [email protected] Subject: Adjusting Pump Curves for Pump Speed This is something I should know, but how are pump curves adjusted for pump speed? I'm looking at a curve based on 3450 rpm (60 Hz) and want to adjust it for 2900 rpm (50 Hz). Is this possible? Bill Brooks William N. Brooks, P.E.
