ARTIFICIAL GAS:-The above figures are based upon 2-inch pressure; for higher pressures these figures should be increased by a percentage as shown below: NATURAL GAS:-The above figures for natural gas are based on a gas under 41⁄2 oz. pressure having a specific gravity of 0.62, which is the ordinary gravity of natural gas sold in cities supplied by gas from the Mid-Continent, Pennsylvania and West Virginia fields. When the pressure is greater than 41⁄2 oz. the figures in the table should be increased as shown below: |
