If the cross-sectional area of one thick tube is equal to the sum of the areas of 10 thin tubes, will their flow rates be the same under the same pressure and fluid conditions? Of course, the lengths of the pipes are equal; it’s just that the length of each pipe in contact with the liquid medium (the perimeter of the pipe) is different, so the resistance varies accordingly. How big can the difference be?
Why isn’t anyone answering? Is the question too easy?
If the pipeline is long, the flow rate should be different, which can be seen quite clearly.
Oh, I forgot to ask – the material of the thick tube and the thin tube should be the same, right? In this case, the flow rate is different because the level of resistance varies, and as a result, the pressure loss also differs.
