Abstract A radial heat-flow apparatus has been constructed in Pyrex glass and used for liquid thermal conductivity investigations. The liquid under test fills the 1.25mm space between concentric cylinders and a measured quantity of heat flows inwards. After calibration using liquids of known thermal conductivity, new values are obtained for pyridine and three chlorofluorocarbon oils. The apparatus can also be used for direct determinations when allowance is made for the temperature drop occurring in each of the glass walls. For this purpose, a determination of the thermal conductivity of the glass was made using a similar method. A discussion of the results is included.
