The calculation of flow rate in parallel pipelines
Thread Content
I’m facing a problem now: in the case of parallel pipelines, there is an example in chemical engineering principles where, given the flow rate in the main pipe as well as the length and diameter of each branch pipe, it’s possible to determine the flow rate in each branch pipe However, in actual engineering projects, valves are installed on each branch pipe. If the valve on a particular branch pipe is reduced, what effects will that have? Will the flow rate in the main pipe change? Has the flow rate of the other branches also changed?
Q=AV, where A is the area and V is the velocity. In the situation you described, I think the velocity in each branch pipe will increase; the total flow rate will change, but not by much. That’s my personal opinion
