In the webpage on head loss link, it was
determined that both
frictional losses and minor losses in piping
systems were proportional to the square
of the flow velocity. Since flow velocity
is directly proportional to the volumetric
flow rate, the system head loss must
be directly proportional to the square of the
volumetric flow rate. From this relationship,
it is possible to develop a curve of
system head loss versus volumetric flow rate.
The head loss curve for a typical piping system
is in the shape of a parabola as shown in
Figure 9.
