A plate-type solar energy collectorr with an absorbing surface covered by a glass is to receive an incident radiation of 800 W/m2. The glass plate has a reflectivity of 0.12 and a transmissivity of 0.80. The absorbing surface has an absorptivity of 0.90. The area of the collector is 5 m2. How much solar energy in watts is absorbed by the collector?
ANSWER: 3060 WATTS
Two plates are separated by two radiation shields with emissivities of 0.10 and 0.15for both sides. The two plates are said to have maintained uniform temperatures600 K (emissivity = 0.6) and 300 K (emissivity = 0.7). Calculate the net rate of heattransfer (W/m2) between the two plates with and without the shields per unitsurface area. Determine the rate of heat transfer (W/m2) between the two plateswhen one plate (emissivity = 0.10) is removed. Assume that the temperatures ofradiations shield are in steady operation.
Thermal radiation strikes a surface which has a reflectivity of 0.55 and a transmissivity of
0.032. The absorbed flux as measured indirectly by heating effect works out to be 95W/m,
then the rate of incident flux is
W/m
