A surface is exposed to solar radiation. The direct and diffuse components of solar radiation are 350 and 250 W/m2, and the direct radiation makes a 35° angle with the normal of the surface. The solar absorptivity and the emissivity of the surface are 0.24 and 0.41, respectively. If the surface is observed to be at 315 K and the effective sky temperature is 256 K, the net rate of radiation heat transfer to the surface is
(a) −129 W/m2
(b) −44 W/m2
(c) 0 W/m2
(d) 129 W/m2
(e) 537 W/m2
