The solar collector surface and its glass cover are spaced 20 mm apart from each other. The emittance of the plate is 0.10 and its temperature is 70 C. The emittance of the of the glass cover is 0.88 and its temperature is 40 C. If the convective heat transfer coefficient between two plate is 4.8 W/m2.K, then estimate the total heat transfer between two plates.
