Question: 131 a thin plate 50 cm by 50 cm is...

Question details

1-31 A thin plate 50 cm by 50 cm is subjected to 400 W of heating on one surface and dissipates the heat by combined convection and radiation from the other surface into the ambient air at 290 K. If the surface of the plate has an emissivity 09 and the heat transfer coefficient between the surface and the ambient air is 15 W/(m C), determine the temperature of the plate. Answer: 362.2 K
