"Many studies of heat transmission have been carried out on various kinds of surfaces. But relatively few investigators have studied the loss of heat from a painted surface. Any surface will lose or gain heat by one or more of the three mechanisms of heat transmission: conduction, convection, and radiation. These mechanisms are thoroughly discussed by McAdams.
Heat transmission can be analyzed by determining thermal conductivity for conduction, overall coefficient for convection, and emissivity for radiation. The resistance concept is useful in indicating the various components of the overall coefficients and in analyzing problems in thermal conduction.
In studying heat flow through a painted surface, early investigators did not use the resistance concept. These investigators heated their apparatus with either electricity or steam.
Equipment is quite often painted as a means of protecting and decorating. A thorough study of heat transfer through painted surfaces has not been made, and many of the investigations present qualitative results.
The object of this investigation was to determine heat lost from a painted pipe about 50 ⁰F above a room at 70 ± 20 ⁰F and determine heat transfer coefficients of paint films and the effect different pigments have on the coefficients"--Introduction, page 1.
