Abstract : Experiments were conducted on study of heat exchange during motion of air in relatively short pipes in range of Reynolds numbers 1,000 to 50,000 with consideration of initial turbulence of flow. Experimental material was a segment of EYalT steel seamless pipe with internal diameter 51mm, wall thickness 1.5mm, and 4,000mm length. Conditions for experiment are described in detail. Results of experiments were processed to obtain dependence of average and local Nusselt number on Reynolds number at different sections of pipe for different magnitudes of Karman number.
