Consider fully developed laminar flow of an incompressible and constantproperty fluid in a flat channel, shown in Figure P 4.6. One of the walls is adiabatic while the other wall is subject to a constant heat flux. Derive an expression for Nusselt number.

Hint: Thermally developed flow requires that
