Consider airflow over a flat plate of length L?1munder conditions for which transition occurs atxc?0.5 m based on the critical Reynolds number,Rex,c?5?105.(a) Evaluating the thermophysical properties of air at350 K, determine the air velocity.(b) In the laminar and turbulent regions, the local con-vection coefficients are, respectively,where, at T?350 K, Clam?8.845 W/m3/2?K, Cturb?49.75 W/m1.8?K, and xhas units of m. Develop anexpression for the average convection coefficient, lam(x), as a function of distance from the leadingedge, x, for the laminar region, 0?x?xc.(c) Develop an expression for the average convectioncoefficient, turb(x), as a function of distance from theleading edge, x, for the turbulent region, xc?x?L.(d) On the same coordinates, plot the local and averageconvection coefficients, hxand , respectively, as afunction of xfor 0?x?L
