Descripción : | We present the implementation of an automated system based on the hot-wire technique for measurement of the thermal conductivity of
liquids using high precision equipment (current source and voltage meter) that allow to work without an array of resistances known as a
Wheatstone bridge, commonly used in such equipments. We also use a criterion to verify that we are working on the correct linear region of
the curve ¢T versus ln(t), which is used for experimental data processing. Finally we validate the functionality of the hot-wire experimental
array by measuring the thermal conductivity in samples of liquids with well-known thermal properties. INSTITUTO POLITECNICO NACIONAL, CONACYT |
