Consider the flow of air over a flat plate under laminar flow conditions at 1 atm. Investigate the influence of temperature on the heat transfer coefficient by examining five cases with constant free-stream temperature of 20C, constant free- stream velocity, and surface temperatures of 50, 100, 150, 250, and 350C. What do you conclude from this analysis? From the results, determine an approximate variation of the heat-transfer coefficient with absolute temperature for air at 1 atm.
