Cancillo, J. Morales, M. Gallego, J. Vaquero, J. Garcia, A. Serrano, V. Mateos] A least‐squares method is used to determine the heat transfer coefficient H of a solid copper bar in air at constant temperature. For this purpose, twelve steady states and their corresponding cooling curves were measured with temperature excesses of the metal over the surrounding air in the range of 11-74°C and were compared to those calculated using a mathematical model to solve the equation for the heat flow in the bar. The model reduces an experimental double exponential law to an overall single exponential and gives similar behavior, within 10% of statistical uncertainty, for H in the steady state and in cooling. The values obtained in this study are in qualitative agreement with the values given in the literature under similar experimental conditions, but there it is not specified how they are obtained in solids.
