Webbför 14 timmar sedan · To evaluate the stability of mixtures of hydrogen and natural gas, National Grid experimentally tested a simulated distribution natural gas pipeline with blends containing hydrogen at up to 50% by volume. The pipeline was outfitted with ports to extract samples from the top and bottom of the pipe at intervals of 20 feet. http://www.bareactslive.com/ACA/act3721.htm different regions of the spineWebbQ = Volumetric flowrate (m 3 /s) D = Pipe diameter (m) u = Fluid velocity in pipe (m/s) Note that the velocity will be constant for a non compressible fluid but will vary with a compressible fluid such as a gas. For a gas it is therefore necessary to slice the pipe layout in several sections in order to recalculate the velocity along the pipe. former cubs second baseman
