How to determine the pipe diameter given the liquid level difference and flow rate
Thread Content
I would like to ask an expert: the liquid level difference between the two devices is 0.5 meters, the flow rate is 600 cubic meters per hour, the pipe length is 40 meters with 3 bends. The liquid is similar to tap water. Will a DN600 pipe be suitable for this application?
The algorithm is quite complex, and few people understand it. There’s a formula provided by qugd in the reply to a post on the forum
Based on 20570, the water flow rate should be between 0.5 and 2 m/s, which should be sufficient
When using gravity flow, it is necessary to utilize flow rate and height difference to calculate the flow velocity, and the pipe is not filled to capacity
It seems it might not work; a half-meter height difference, with pipes 40 meters long. It is recommended to add a pipeline booster pump. The calculation is also simple. There are small software programs.
