How to determine the pipeline purging speed in chemical plants

The purging plan stipulates that the gas purging flow velocity must not be lower than 20 m/s, and the water washing flow velocity must not be lower than 1.5 m/s. In actual operations, how can we determine whether the purging velocities meet these requirements?

Purging is divided into continuous purging and burst purging; for continuous purging, the flow rate can be determined based on flow rate and pipe diameter, while for burst purging, the burst pressure is determined first

How is it determined, in the context of blast cleaning, what pressure is sufficient to meet the requirements?
