O The speed of the fluid is constant throughout the volume of the pipe. O The speed of the fluid is greatest near the center of the pipe. O The speed of the fluid is greatest near the walls of the pipe. A viscous fluid is flowing through two horizontal cylindrical 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 Qg in the longer pipe compare to the volume flow rate Qa in the shorter pipe? P2 P2 2L O Qa is the same as QB - O Qa is twice as large as QB . O Q, is one-fourth as large as QB . O Q, is half as large as QB .
