07.12 How do I size the inlet piping for the day tank?

For on-board day tank pump systems, the inlet piping should be at least the size of the pump inlet, and most likely will be increased to allow for calculated line losses on the suction side.

Remote pump systems should be sized for 2 considerations: (a) minimize line losses at full flow conditions to a maximum of about 70 kPA, and (b) size the piping sufficiently to make sure that the last generator in a series, is not starved for fuel.
