The spectral emissivities, at an effective wavelength of 0.65 microns, and total normal emissivities, were determined for machined and polished surfaces of the graphites Great Lakes Carbon H1LM and H3LM, and Speer 7100. The spectral emissivities were investigated within 1000 to 3000 C. For machined surfaces, the spectral emissivity decreased with increasing temperature from 0.87 to 0.81 for H1LM; from 0.87 to 0.83 for H3LM; and from 0.87 to 0.78 for Speer. For polished surfaces, the spectral emissivity remained constant with increasing temperature and the mean value was 0.855 for H1LM; 0.777 for H3LM; and 0.820 for Speer 7100. The total normal emissivities were investigated from 1600 to 3000 C. For machined surfaces, the mean value of the total normal emissivity was 0.852 for H1LM; 0.852 for H3LM; and 0.847 for Speer 7100. For polished surfaces, the mean value of the total normal emissivity was 0.802 for H1LM; 0.808 for H3LM; and 0.800 for Speer 7100. (Author).

This extensively revised 4th edition provides an up-to-date, comprehensive single source of information on the important subjects in engineering radiative heat transfer. It presents the subject in a progressive manner that is excellent for classroom use or self-study, and also provides an annotated reference to literature and research in the field. The foundations and methods for treating radiative heat transfer are developed in detail, and the methods are demonstrated and clarified by solving example problems. The examples are especially helpful for self-study. The treatment of spectral band properties of gases has been made current and the methods are described in detail and illustrated with examples. The combination of radiation with conduction and/or convection has been given more emphasis nad has been merged with results for radiation alone that serve as a limiting case; this increases practicality for energy transfer in translucent solids and fluids. A comprehensive catalog of configuration factors on the CD that is included with each book provides over 290 factors in algebraic or graphical form. Homework problems with answers are given in each chapter, and a detailed and carefully worked solution manual is available for instructors.
