2. Determine the diameter of a landfill gas header pipe (assuming SDR17) for the following conditions. Calculate the pipe velocity for a range of pipe diameters (starting at 6 inches and ending at 48 inches). a. Quantity of flow to be handled is 5,000 ft³/min; temperature of 100°F; pressure (or applied vacuum) of 40in.WC. The gas composition is 50% methane, 48% carbon dioxide, 2% air. The elevation at the site is 560 feet. [Assume concurrent flow (gas and water flowing in the same direction; maximum design velocity of 40 ft/sec)].
