Pipe flow rate of DN25

This post was last edited by sxf1028102800 on 2018-2-4 22:59 For a DN25 pipe, the water flows in the pipe. How many cubic meters can the water flow at most under normal pressure? Thanks, extra points
Normally calculated based on the flow rate of 2 meters/second.
The flow rate of water under 0.1MPa pressure can be calculated as 0.5m/s. formula: Cross-sectional area πR2 × 3600 seconds × 0.5m/s, approximately 0.9 square meters per hour
If it is normal pressure and there is no position difference, can it flow?
The water velocity in a normal municipal pipe network is 1~2m/s, and the flow rate is about 0.0005~0.002 cubic meters/s.
According to the "Petrochemical Equipment Pipeline Installation Design Manual", the flow rate of water medium in DN25 pipelines is 0.6~0.9m/s, which means that the flow rate of the pipeline should be between 1.1~1.5m3/h
Artesian pipe, flow rate please refer to HG/T20570
The thinner the tube, the greater the frictional resistance. Therefore, the value of flow rate should be appropriately smaller.
Is there no parameter at all for the disparity slope?
