2. A triangle. An isosceles triangle (blue triangle in the figure. H = 10 cm and L = 20 cm) is drawn on a semi-infinite flat plate at a uniform surface temperature Ts = 100C. Consider laminar uniform flow of constant properties fluid over the plate where T = 20C. (a) Determine the convective coefficient. Hint: Use the similarity solution. (b) Determine the heat transfer rate between the triangle area and the fluid using the chart given. 1 W/mK, v = 10-6 m/s, Pr = 5.
