How to calculate the pressure loss in a double-pipe system? ?
Thread Content
As shown in Figure 2 above, it is a double-tube structure; the inner tube has a DN40 diameter, and the process medium is used； Outer pipe DN65, warm water. Now that the required length of the double pipe and the flow rate of warm water are known, how can the pressure loss in the warm water sleeve be calculated? And how should the head of the warm water pump be determined? ? Please, experts in this field, share your thoughts.
Hasn’t everyone encountered this problem? ?
The pressure drop of the jacketed pipe – is your pipeline very long?
You can consider estimating a value that is slightly higher than the resistance drop of a single tube
What is the single-tube method? For DN40 fitted with DN65, what is the equivalent ring radius?
Personally, I think it should be calculated based on a DN40 pipe diameter, because the smaller the diameter, the greater the resistance
Keep going! I hope everyone can help take a look again
