Mechanical Engineering
At a time on the sunny day of July 21, the sun shining onto thewall and window at an incident angle of 30 while the incidentangle onto a horizontal surface is measured at 45. Assume thewindow glass have the properties of τD = 0.7; τd = 0.6; αD = 0.1;αd = 0.3. The emissivity of the wall is 0.9. Calculate:
Total solar radiation absorbed by the wall;
Total solar radiation into the room via window;
Total solar radiation reflected away by the window glass
