What does c=0.8 mean in many P&ID diagrams?

Look, what is it marked on? Look carefully at the image on the home page; maybe there’s an explanation in one of the lines of text~

The first thing that comes to mind is a welding coefficient of 0.8, but this is probably the minimum requirement
It would be best to include a flowchart; are you referring to the proportional coefficient for the traffic values? A pipe slope is still required; if there is a slope, it’s a fairly large one
If there is no image for the home page, just ask the engineering company; logically, an image should be available for the home page
