Pump affinity
WebThe affinity laws for centrifugal pumps state that the H/Q curves at various rotational speeds can be derived from the following relationship as conventionally represented: Q Flow rate H Head Y Specific energy n Rotational speed. If P Q = ρ · g · Q · H (see Pump power output) and P = P Q / η (see Pump power input), and assuming a constant density (ρ) of …
