A solid rod of radius 1 cm is placed in a pipe of radius 3 cm so that their axes are aligned. Water flows

through the pipe and around the rod. Find the flow rate if the velocity of the water is given by the radial

function v(r) = 0.5(r − 1)(3 − r) cm/s.

Step 1

velocity of water v(r) = 0.5(r − 1)(3 − r) cm/s.

flow rate is given as,

Step 2

Limits for r would be from 1 to 3
