Abstract
A distribution manifold includes a main trunk line at a first end of the manifold proximate a boost pump, two branch lines at a downstream end of the main trunk line, a first Y-connector coupling upstream ends of the two branch lines to the downstream end of the main trunk line, two sub-branch lines at a downstream end of each of the two branch lines, and two second Y-connectors coupling upstream ends of the four sub-branch lines to the downstream ends of the two respective branch lines. A sum of cross-sectional areas of downstream ends of the four sub-branch lines is equal to the cross-sectional area of the upstream end of the main trunk line.
