Run as big as you want up to it and then reduce before going into the bulkhead.

Ah, the Darcy formula. So scientific looking but doesn't really work here.+1 Thank you for the correct information.
Lot of people still do not understand water pressure is the same regardless of pipe diameter. Smaller diameter actual have more restrictions and head pressure loss.
HL = (F) X (L/D) X (V^2/2g)
HL = Total Head Loss
F = Friction factor related to the roughness inside the pipe
L = Length of the pipe
D = Diameter of the pipe
V = Average liquid velocity in the pipe
2g = Two times the Universal Gravitation Constant (g=32.2 ft/sec)
