In the selection of an opaque surface to act as collector of solar energy. It would be desirable for the surface to have which of the following sets of characteristics?
-
- Absorptivity for radiation in the visible spectrum = high emissivity for low temperature radiation = low convective heat transfer coefficient = low
- Absorptivity for radiation in the visible spectrum = high emissivity for low temperature radiation = high convective heat transfer coefficient = low
- Absorptivity for radiation in the visible spectrum = low emissivity for low temperature radiation = high convective heat transfer coefficients = high
- Absorptivity for radiation in the visible spectrum = low emmissivity for low temperature radiation = high convective heat transfer coefficient = low
Correct Option: A
NA
