A horizontal thin plate with a length of L= 10 cm is tiled with a constant heat flux from the bottom and is cooled by air at the top. The air velocity is U = 40 m / s and the temperature is 20 ° C. What should be the minimum heat flux so that the plate temperature does not exceed 80°C? (kW / m²) v 17.94 x 10-6 m²/s = 0.0277 W/(m.K) Pr = 0.71
