Question: 130 a thin plate is exposed to an infrared radiation...

Question details

1-30 A thin plate is exposed to an infrared radiation flux of 1500 W/m2 on one surface while the other surface is kept insulated. The exposed surface absorbs 90 percent of the incident radiation flux and dissipates it by convection and radiation into the ambient air at 300 K. If the heat transfer coefficient for convection between the surface and the ambient air is 15 W/(m2 °C), determine the temperature of the plate. Take the emissivity of plate as ε 09.
