Answer 1

Answer:

The outside wall temperature is 35°C. The top and side walls are covered by a ... convective heat transfer coefficient is 250 W/m 2 . ... Surface emissivity and absorptivity to solar radiationT2 ≤ 38°C, with different wall thermal conductivities, k. ... emissivity and absorptivity on steady-state temperature. ... FIND: Surface temperature without and with incident solar radiation.Absorptivity is the fraction of radiation incident on a surface that is absorbed by ... equivalent but “more correct” unit of thermal conductivity is W⋅m/m2⋅°C that indicates product of heat.related to the theoretical equivalent sol-air temperature and the external ... external surface thermal resistance (m2K/W).
