“…From 1951, Grayson [5][6][7] discussed the use of the apparatus for measuring the thermal conductivity, taking into consideration a steady-state regime in which the relation between heat production and heat loss is represented by equation (2), described by Carslaw [8] in 1921 for an electrically heated spherical source in an infinite mass of material. In 1968, Chato [9] was to first to use a thermistor as temperature sensor and heating element for measuring thermal conductivity and thermal diffusivity of biological materials. Several other researchers have also applied the thermistor method for measuring thermal properties of biomaterials [10][11][12][13][14][15].…”

Abstract. The study and the development of measuring methods of thermal conductivity are essential in several engineering applications, since as a consequence of the current justified demands on saving and rational use of thermal energy, the heat transfer with the maximum efficient as possible is of great relevance. The measurement of the water content is also a relevant parameter in several research areas and industrial sectors, since the quantity of water in the substances influences several biological, chemical and physical processes. The aim of this paper is to present an experimental and theoretical study, following the good metrological practices, of a method based on a spherical heat source in order to measure the thermal conductivity of liquids, focusing on water, ethanol and their mixtures, with later determination of the water content of the binary samples.
