What will happen if the pipeline size is chosen too large?
Thread Content
Generally, what flow rate corresponds to what pipe diameter? It should be fine to use a pipe one or two sizes larger. But what happens if the pipe size is chosen too large? For example, if I have a flow rate of 50 cubic meters per second, but I use a 500 mm diameter pipe with a length of 100 meters, transporting the fluid to a height of 10 meters, then according to simple calculations of pipe losses, there should be no loss; in that case, a head of 10 meters would be sufficient. At most, I might add a margin of 2-3 meters and choose a pump with a head of 13 meters. But could there be other factors in reality, such as diffusion losses? I would appreciate advice from those who have experience in this area
Using larger pipes has an impact on pressure and head, especially the head.
