Question
A one-dimensional plane wall is exposed to convective and radiative conditions at x = 0. The ambient and surrounding temperatures are T = 20°C and Tsur = 40°C, respectively. The convection heat transfer coefficient is h = 20 W/m2-K, and the absorptivity of the exposed surface is a = 0.78. Determine the convective and radiative heat fluxes to the wall at x = 0, both in W/m2, if the wall surface temperature is T; = 29°C. Assume the exposed wall surface is gray, and the surroundings are large. g'onv i W/m? %3D i W/m2
