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. 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.
Commercial Liquid Propane Pipe Sizing: Key Principles and Best Practices
Liquid propane pipe sizing, however, deals with a higher density fluid transported at significantly elevated pressures, often exceeding 250 psi at the source. Velocity is the speed of the gas moving through the line; keeping velocity within an optimal range prevents erosion, noise, and pressure fluctuations.
If the drop is too severe, the appliance may fail to ignite or operate safely. 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.

It is important to note that these charts typically assume standard natural gas pipe materials, such as black steel or approved CSST, and may require derating for extreme temperatures or specific insulation scenarios.
