Seeking help with pipeline design

I’m not sure what effect the connection of these two pipelines will have on the pipe that has a bend above them. The upper pipe is 250 mm in diameter, while the lower pipe is 300 mm in diameter. Usually, when driving, one first drives down the pipeline and then up it. Thank you! When the upper and lower pipes meet end to end, could this cause the upper pipe to stop flowing or have too low a flow rate?
Please, the original poster, explain your question clearly. Do you want to know the flow distribution between two pipes? Flow distribution is inversely proportional to the square of your pipeline pressure drop. If there are many bends, the flow rate will definitely be lower. If you want to know the specific flow rate, you can use pipeline network calculation software to figure it out.
This is a matter of balancing system resistance; the pressure as well as the resistance are the same at both the branching points and the convergence point. Due to the different pipeline characteristics of the two branches, after the fluid splits, this balance is automatically achieved based on the volume of flow – more flow is directed to the branch with lower resistance, while less flow goes to the branch with higher resistance – and the flow balance is established automatically at the convergence point
