Question

Use k=320 W/mK for your calculation

w m-K Two-Dimensional Steady and transient Conduction - Heat Sink Aluminum fins with triangle profiles (k = 370- p=2800 kg 900 shown in the accompanying figure, are used to remove heat from a surface whose temperature is Tg = 150°C. The temperature of the surrounding air is 20°C. The natural heat transfer coefficient associated with the surrounding air is h = 190- Determine the temperature distribution along a fin. w m- T., 20 mm 150°C 90 mm kg-K A) Aluminum Heat sinks of rectangular profile (k = 170 RIPE 2800 kg, c = 870 ) are commonly used to remove heat from a surface whose temperature is T, = 150°C. The temperature of the surrounding air is 20°C. The natural heat transfer coefficient associated with the surrounding air is h = 168 Determine the temperature distribution along a fin.
