Question:

Referring to Figure 8.11 consider conditions in an annulus having an outer surface that is insulated (q: = 0) and a uniform heat flux q"i at the inner surface. Fully developed, laminar flow may be assumed to exist.

(a) Determine the velocity profile u(r) in the annular region.

(b) Determine the temperature profile T(r) and obtain an expression for the Nusselt number Nui associated with the inner surface.
