Relationship between flow rate, flow velocity, and pipe diameter. block. You can determine the pressure drop for your system by measuring PSI at the air compressor and at the point of use. Velocities should be held to <= 25 fps in steel pipelines. Other materials that are not as corrosion resistant can be used as a cost-effective solution with some H2S removal technology applied upstream of this piping. Your airflow is measured in cubic feet of air per minute, or CFM. The sizing shall be based on the flow and the available pressure, is there any additional factor that should be considered? To determine the size of each section of pipe in any system using piping specific table*, and proceed as follows: (1) Measure the length of the pipe from the gas meter location to the most remote outlet on the system. The calculation is a little complicated. The initial drop of piping, points of pressure change, and/or major equipment should have a condensate/sediment trap for the higher rate of condensation that can occur at these points and to remove particulates that may be in the biogas.
