A solar collector has a glass cover plate and an absorber plate separated by an air space. The collector is square, 1 m by 1 m, and is tilted at an angle of 20 degrees from the horizontal. The cover plate is at 30 C and the absorber plate is at 60 C. What is the rate of convective heat transfer across the air space if (a) the air space is 2 cm thick? (b) the air space is 4 cm thick?
