WebA.2.2 Low pressure natural gas tables.. Capacities for gas at low pressure [less than 2.0 psig (13.8 kPa gauge)] in cubic feet per hour of 0.60 specific gravity gas for different sizes and lengths are shown in Tables 402.4(1) and 402.4(2) for iron pipe or equivalent rigid pipe; in Tables 402.4(8) through 402.4(11) for smooth wall semirigid tubing; and in Tables … Webout to the system. There are pipe sizing charts that have calculated the pressure drop in foot head of energy loss for any flow rate through any size pipe. Of course, there are standard piping prac-tices that limit the amount of GPM for a given pipe size. There are two reasons: 1. Velocity concerns—the speed at which the water
