Comb<strong>in</strong>e pipes <strong>in</strong> series with demandless nodes /<br />
<strong>in</strong> parallel to <strong>uni</strong>que pipe<br />
• Pipes <strong>in</strong> series with junctions, which have no demand, has the<br />
same hydraulic effect as one pipe with an equivalent<br />
conductance/resistance value and thus can be substituted<br />
(R=R1+R2)<br />
• Parallel pipe can be substituted with a <strong>uni</strong>que pipe, which has the<br />
aggregate conductance of the orig<strong>in</strong>al ones (1/R = 1/R1 + 1/R2)<br />
