For steel, NFPA uses weight density of 490 lbs/ft^3, and for water, 62.4. Figure the area (ft^2) based on the O.D., minus the area based on the I.D. (ft^2) times 490 is the weight of the steel per foot. Add the weight of the water per foot, which is the area based on I.D., times 62.4. Ex--- 2.5" Sch07 I get 4.693 lb/ft. ((2.875/24)^2)*PI=~.0044 ft^2. ((2.731/24)^2)*PI=~.0407 ft^2.
Brad Thanks, I had found this one but noticed that some of the numbers are lower that the sch 5 chart in NFPA 13, would have thought they would be somewhere in the middle due to the thicker wall on sch 7 pipe.
