The velocity profile in a channel carrying a very viscous liquid is approximated by = 3(e0.2 - 1) m/s, where y is in meters. 0.4 m u = 3 (e0.2y-1) m/s Tap image to zoom Part A Determine the average velocity of the flow. The channel has a width of I m. Express your answer to three significant figures and include the appropriate units.
