The analysis in Subsection 13.5.1 assumes symmetric boundary conditions. This assumption will not apply, for example, when the two boundary surfaces are at different temperatures. Consider Figure P13.16, and assume that

Derive an expression for u(y). Also, assuming that PKn_2b
= const. and neglecting density variations that are due to changes in temperature, use that expression to prove that the total mass flow rate will be
