description abstract	A previous analysis of turbulent flow and heat transfer in smooth tubes with variable fluid properties was modified in order to be applicable to air which has a Prandtl number slightly less than unity (O.73]. In order over to verify the analysis, tests were conducted to determine local heat-transfer coefficients and friction factors for fully developed turbulent flow of air in a smooth electrically heated tube having an inside diameter of 0.87 inch and a length of 87 inches. The tests were conducted at high ratios of wall to fluid bulk temperature. Velocity and temperature profiles were measured for some conditions.
