A collector has a single cover of low-iron glass. It is at a latitude of 48 and a slope of 63. For a particular hour, the angle of incidence of beam radiation on the collector (taken as that at the half-hour point) is 10.7 and the zenith angle is 71.3. I = 1.03 MJ/m and I = 1.62 MJ/m. Ground reflectance is 0.4. The cover is glass with KL = 0.013. The absorptance of the plate for total radiation at normal incidence is 0.955, and it has an angular dependence as shown in Figure 4.11.1. a What is (T)? b What is (T)d? What is (T)? d Calculate S for the hour.
