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

Derive an expression for u(y). Also, assuming that PK_n2b
= 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
