4.12.2 Fluid velocities and flow rates
For the different media in piping, WinGD provides recommended fluid veloci-
ties and flow rates as stated in the document ‘Fluid Velocities and Flow Rates’
(DG9730). The pump delivery head proposals provided by the GTD are based on
system layouts which follow these recommended values. However, the values
which are provided by this document are only for guidance purposes and the
final pump layout must account for the final system layout. The values are based
on the optimisation between installation and operating costs (pump energy). Na-
tional and shipyard standards may also be applied.
