Question:
The absorber surface of a solar collector is made of aluminum coated with black chrome (αs = 0.87 and ε = 0.09). Solar radiation is incident on the surface at a rate of 600 W/m2. The air and the effective sky temperatures are 25°C and 15°C, respectively, and the convection heat transfer coefficient is 10 W/m2 · K. For an absorber surface temperature of 70°C, determine the net rate of solar energy delivered by the absorber plate to the water circulating behind it.
