Abstract

An Experimental test rig has been manufactured to measure a horizontal painted iron plate's emissivity. This plate was painted with two different colors. The first color was semi-black, and the other color was semi-white. The test was carried out at temperatures range between 52 ° C and 125 ° C. The results showed that the plate's emissivity with semi-black surface color was higher than the same plate's emissivity but with the semi-white surface color. The results also showed that the emissivity increases with increasing temperature for both color cases.
