How is the flexibility of this operation used to determine the pipe diameter and flow rate?
Thread Content
Now, we need to design a component for which there is an optimal flow velocity range of, say, 2–2.5 m/s, at which 110% of the capacity is achieved. So, what diameter should be chosen? Should it be based on 110% of 2.5 m/s, or 110% of 2.3 m/s? ? 110% 2m/s? ? Still 100% at 2.3 m/s? ? 100% 2m/s? ? I earnestly ask experts to share their insights!

I think 100% at 2 m/s should work, but it depends on the specific flow rate; it shouldn’t be a problem if the pipe is made slightly larger
If the properties of the material are relatively dangerous, it’s better to use the lower limit; generally, using the middle value is sufficient. In your case, to achieve 110% capacity, it’s best to keep the flow rate below 2.3 m/s, so that the flow rate remains within the economically optimal range when 110% capacity is attained.
Calculate it at 110% of the traffic volume.
It can be calculated at 110% of the traffic volume!
In my opinion, the flow rate should be set higher, provided that safety is ensured
I agree with what was said above: as long as safety is ensured, a higher flow rate is very beneficial – it’s cost-effective and aesthetically pleasing, plus installation is easier.
