Problem 2 (30 points) Consider fully-developed laminar flow between two parallel plates. Uniform inward heat fluxes q' and q are applied at the top and bottom plates, respectively. Obtain the Nusselt numbers Nuj and Nuz based on the respective fluxes. Note that dT (2)/dz depends on the combined heat input, and Nui values will depend on the ratio of the fluxes. The hydraulic diameter in this case can be taken to be the limiting case for a very oblong rectangle. =q1 y= 1 w(y) ! y = 0 11 q" = 92
