Answer 1

Dr. DONALD R. PITTS holds three engineering degrees— the B.M.E.  

from Auburn University, the M.S.M.E., and Ph.D. from the Georgia  

Institute of Technology. His 27 years of academic experiences include  

appointments at Tennessee Technological University, Clemson University,  

and the University of Tennessee-Knoxville. All of his university  

assignments have been in teaching and research in the Thermal Sciences

periences include one year as a Program Manager at NSF and one year as  

Director, Tennessee Energy Extension Service. Dr. Pitts has coauthored  

one major textbook and one Schaum’s Outline, both in the heat  

transfer/ftuid mechanics area. He has authored or coauthored 20 refereed  

research papers and major reports, and he is thoroughly qualified to write  

on the topic of Heat Transfer.  

Dr. LEIGHTON E. SISSOM is a registered professional engineer. He
