Issues with pipes and flow rates
Thread Content
What is the maximum flow rate for different pipes? How should it be calculated? Is there a corresponding formula? For example, what are 200, 250, 300, and 350 respectively?
There is no such thing as a maximum flow velocity; the diameter of the pipe to be used depends on the flow rate. Generally, there is an optimal range for flow velocity, and relevant design documents can provide details on this. For liquids, the flow velocity is usually around 1–3 m/s, while for gases it’s around 20–30 m/s. The pipe diameter is then chosen based on the flow rate, with slight rounding applied to make it convenient.
Borrowing a solution from elsewhere: http://bbs.hcbbs.com/thread-344380-1-1.html. The flow rate is closely related to the type of medium and the pressure of the medium; it is also related to the pipe diameter, but to a lesser extent.
Thank you. The pressure on the front end is 8000 Pa, and the pressure on the back end is 3000 Pa. What are the maximum flow velocities corresponding to these pipe diameters?
It mainly depends on the medium… The fundamental difference between gases and liquids is that there’s a speed difference of almost 10 times. And with such a large pressure drop, it’s not just due to pipeline resistance, right? For the specific calculations, you can look it up in a book on chemical engineering principles or something similar; I’m sorry, I can’t help you calculate it……
I’m sorry, I didn’t explain it clearly; it’s the gas flow rate
What anger? Air? Steam? (Pressure rating? ) Hydrogen? It’s different.
The air speed is generally 10 m/s to 30 m/s
