Question

(25 points) Air at atmospheric pressure and a temperature of 25°C is flowing over a 1-m long flat plate that is heated from below with a constant surface heat flux of 1250 W/m². Part 1: (a) For a velocity of $u_\infty$=0.1 m/s, calculate the Reynolds number, is the flow laminar or turbulent? (b) For a velocity of $u_\infty$=0.1 m/s, calculate the convection coefficient $h_x(L)$ at the trailing edge where x=L. Part 2: (c) For a velocity of $u_\infty$=15 m/s, calculate the Reynolds number, is the flow laminar or turbulent? (d) For a velocity of $u_\infty$=15 m/s, calculate the convection coefficient $h_x(L)$ at the trailing edge where x=L. Part 3: (e) Compare the results of parts 1 and 2, what conclusion can you draw from changing the velocity about the convection coefficient and flow behavior? Discuss your results in 2-3 sentences. Properties of Air: v=18.76x10$^{-6}$ m²/s k=0.0284 W/mK Pr=0.703
