For carbon steel pipes with a pressure rating of 0.3Mpa and DN300, how can the flow rate of water in such pipes be estimated?

The last edit to this post was made by security on 2011-7-10 at 14:37. I would like to ask everyone: For a DN300 carbon steel pipe, with an inlet pressure of 0.3 Mpa, what is the estimated water flow rate?
Generally, the flow rate of water can be taken as 2 m/s; in that case, your flow volume can be 500 m3/h.
The designed flow velocity for water is generally 1–3 m/s, but now I want to estimate the flow rate under increased head pressure; it’s about estimating the transport capacity!
Reply to 3# cnsttop: For industrial water supply with a pressure of <0.8 Mpa, a flow rate of 1.5~3.5 m/s is recommended.
I usually estimate it at a flow rate of 2 meters per second, as that’s a safer figure; in reality, it should be above 2 meters per second.
