Problem 15HP
A flat channel of depth 1 m has a fully developed laminar flow of air at P0, T0 with a velocity profile of V = 4Vcx(H − x)/H2, where Vc is the velocity on the centerline and x is the distance across the channel, as shown in Fig. P4.15. Find the total mass flow rate and the average velocity both as functions of Vc and H.
