Consider parallel flow over a flat plate for air at 300 Kand engine oil at 380 K. The free stream velocity isu??2 m/s. The temperature difference between thesurface and the free stream is the same in both cases,with Ts?T?.(a) Determine the location where transition to turbu-lence occurs, xc, for both fluids. (b) For laminar flow over a flat plate, the velocityboundary layer thickness is given byCalculate and plot the velocity boundary layerthickness ?over the range 0?x?xcfor each fluid. c) Calculate and plot the thermal boundary layerthickness ?tfor the two fluids over the same rangeof xused in part (b). At an x- location where bothfluids experience laminar flow conditions, explainwhich fluid has the largest temperature gradient atthe plate surface,??T/?y?y?0.
