WebNatural Gas Pipe Sizing Tables and Charts Steel Pipe - Schedule 40. Downstream Pressure. inlet upstream pressure is more than 5 psig (35 kPa) fittings factor 1.2 - equivalent pipe length = pipe length + 20%; For natural gas the nominal BTU/cf varies from about 900 to 1100 BTU/cf. In general it is common to set. 1 Cubic Foot (CF) = Approx 1,000 BTUs WebPSIG = PSIA – 1 atm = PSIA – 14.7 PSI. As you can see, to calculate PSIG from PSIA, we need to subtract atmospheric pressure from PSIA. At sea levels, this atmospheric …
