The intersection of these values indicates the acceptable length of the run or the resulting pressure at the appliance. Interpreting the Sizing Chart Standard engineering charts for liquid propane are organized by columns representing pipe diameter and rows representing the calculated load or flow rate.

The chart accounts for these factors by correlating specific flow rates with allowable pipe diameters to maintain pressure drop below 1% to 2% per 100 feet of run. The primary goal is to balance flow capacity against pressure loss to ensure that a 100,000 BTU heater at the end of a 100-foot run performs identically to one connected directly to the manifold.
Undersized piping creates excessive pressure drops that prevent appliances from reaching full power, while oversized lines represent an unnecessary capital expense and can lead to sluggish gas velocity that promotes condensate accumulation. The length of the run is the most obvious variable, as friction loss accumulates over distance.
