Question

2.1 Consider a vertical wall with a specific location/orentation and on a specific dateltime such that the solar altitude angle is β-49, the angle of incidence is θ-60s, and the normal direct iradiation is Go-297.7 Btuhr-A. The diffuse irradiation (Cleaving the "horizontal" sky or incident on a horiaontal surface) can be assumed to be 13.7% of the normal direct irradiation. For this vertical wall, determine the fa, direct solar radiation incident on the wall, (b) diffuse solar radiation incident on the wall, and ic) reflected solar radiation incident on the wall (take the reflectance of the ground to be A-033).
