Fuel Pipe Sizing

Figures 8 and 9 provide the maximum capacity of pipe in
cubic feet of gas per hour for gas pressures of 0.5 psi or less
and a pressure drop of 0.3 in. water column. Specific gravity
of gas is shown.
Listed values compensate for a nominal amount of restriction
from bends, fittings, etc. If an unusual number of fittings,
bends, or other restrictions are used, please refer to federal
and local codes.
