Problem 2 Consider the steady and two-dimensional laminar boundary-layer flow of constant thermophysical properties with constant and uniform free-stream velocity Ue and temperature Tx over a flat plate. Let there be an unheated starting region that extends a distance x0 from the leading edge and the plate be maintained at a constant temperature Tw for x>x0. Assuming linear velocity and temperature profiles in the respective boundary layers and neglecting viscous dissipation, develop an expression for local Nusselt number Nux applicable to such x>x0 where T
