.FreeFluids.Pumps.BumpPumpBase

It extends the PumpBase model and introduces parameters for the pump curve definition. They are flow, head, and efficiency, at two points of the curve, plus the head at zero flow.

It defines three variables for: flow, head and efficiency with a nonviscous fluid.

It defines two equations relating the three variables with the pump speed. So, if the pump speed is fixing, the definition of one of the three variables will allow the calculation of the other two.
