Constant Wall heat flux for turbulent flow between two parallel plates 

(a) Work through the development in S13.4, and then perform a similar derivation for turbulent flow in a thin slit shown in Fig. 2B.3. Show that the analog of Eq 13.4-19 is in which

(b) Show how the result in (a) simplifies for laminar flow of Newtonian fluids, and for "plug flow" (flat velocity profiles).
