A flat-plate solar collector is constructed as shown in figure below. A glass plate covers the blackened surface which is insulated. Solar energy at the rate of 750 W/m? is transmitted through the glass and absorbed in the blackened surface. The surface heats up and radiates to the glass and also loses heat by convection across the ait gap, which has k.=0,042 W/m. C. The outside surface of the glass loses heat by radiation and convection to the environment at 30°C with h= 20 Wim?. C. It is assumed that the glass has e=0,9. The blackened surface is assumed to have =1 for all radiation. Determine the temperature of the glass (T:) and inside surface (T:). (Assume no absorption of the solar energy in the glass. ) (3) Outside T,-30 °c (2) Glass k= 0.042 W/m. °C Ax= 7,5 cm (1) Black body insulation A flat-plate solar collector is constructed as shown in figure below.
