For the first start-up, the purge flow rate must be at least 20, and the washing flow rate must be at least 1.5 m/s. How is this flow rate measured? During normal purging and flushing, the flow meters and other instruments are disconnected; with so many pipelines being purged, how is it possible to measure the flow rate?

Can the flow velocity be calculated based on pressure and pipe diameter?
