A viscous fluid is flowing through two horizontal pipes. The pressure difference P2 – P1 between the ends of each pipe is the same. The pipes have the same radius, although one is twice as long as the other. How does the volume flow rate QB in the longer pipe compare with the rate QA in the shorter pipe?
