Pump Systems The system head generally consists of two parts:-
The difference between the suction and final discharge static
levels in an open system. This is usually independent of flow.
Energy Loss in the Pipework. This is essentially the friction
head loss in the piping and is related to the flow . Under
turbulent flow operating conditions the friction loss may be
assumed to be related to the flow velocity 2. Therefore a
friction loss plot is a parabola passing through the origin. It
is often the case that the static head is small compared to the
friction loss e.g. in Centrifugal pump curve. A typical pump
operating with a set impeller diameter and at a set rotational
speed delivers a head related to the liquid flow rate. The head
is normally highest when no flow is
