What is the difference between the actual flow rate and the standard flow rate in pipeline data? What are their meanings respectively, and where are they used?
For ordinary gases, standard cubic units are used to facilitate calculations. The conversion to actual flow rate is done through temperature and pressure conversion. Roughly, it is calculated using PV=nRT. For liquids, use the actual flow rate.
