Natural Gas flow is given in thousands of BTU/hr. One cubic foot of Natural Gas = roughly 1000 BTU. Typical nominal pressure at the burner for Natural Gas is 3.5" of water column. Typical machine supply pressure is 5" to 7" of water column.
How to size gas piping. The Gas Code contains sizing tables and information that must be used to size most gas systems. Some large commercial and industrial systems fall outside the scope of this book and must be sized by other engineering practices. There are software programs available that will design and size fuel gas piping systems.
