Measure the height of the ceiling. Pounds per square inch (psi) used for measuring gas pressure in the distribution system and. A common operating pressure for natural gas appliances is around 7 inches of water column (WC) or re-stating this in equivalent measure, thats 14.9 millibars or 1743 Pascals or Pa, or about 0.25 psi (pounds per square inch) or about 4 ounces of pressure per square inch. If you encounter this situation this formula might be of help. Beginning in 1965, the pressure base is 14.73 psia at 60 Fahrenheit. Where CFH = Cubic per hour. good discussion of standard conditions. Natural gas is lighter than air (density of air is 1.293 kg/Sm3, density of natural gas is 0.68 kg/Sm3); consequently it rises quickly in air. The capacity of the meter and regulator must be greater than the total sum of the maximum BTU rating of all the appliances in the home.
