    Midterm Exam II Solution‚ ME 342 Fluid Mechanics (Spring 2013) 1. Consider a steady‚ incompressible‚ y=+h b viscous flow of viscosity  due to y a pressure gradient x inside a channel of two fixed u=u(y) plates at a distance of 2h‚ as shown in the figure. Neglect a gravity effect. The channel width y=h b is W and it is very long compared to the channel length L (i.e.‚ W>>L) so that it is still valid to assume that the channel flow is a two-dimensional plane flow ( ) and an axial flow (v = w = 0)
