Sizing of Piping Sections To determine the size of each section of pipe in any system using piping specific table*, and proceed as follows:

Natural gas has about 1,000 BTU per cubic foot while propane packs 2,500 BTU per cubic foot. So if you've got a 100,000 BTU furnace, you need 100 cubic feet per hour of natural gas but only 40 cubic …

Enter these values along with your gas type, and the calculator will reference NFPA 54 capacity tables to recommend the minimum pipe size that delivers adequate flow with a safety margin for future …
