WebApr 16, 2024 · This is the static pressure (resistance) and you can see how it is linked to the cfm. The units to express this is inches of water column (since the measurement classically included how much distance the static pressure displaces a column of water). WebJul 1, 2024 · 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. Pipe length must include additional length for all fittings. Add approximately 5 feet of pipe per fitting. ios system repaire download on pc
