Abstract

A concentric cylinder type cell was designed and constructed tp measure thermal conductivity of liquids. The materials of construction were stainless steel and teflon, so that a wide variety of liquids could be tested.

The systems studied were aqueous solutions of methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, and tertiary-butyl alcohol. Thermal conductivity was studied as a function of composition.

The data obtained were fitted to quadratic equations by least squares analysis. For each system, an equation of the following type was obtained:

k_L = A + Bx_A + Cx_A²

where k_L is thermal conductivity, x_A is weight fraction of alcohol, and A, B, and C are constants. The table below give values of A, B, and C for each system.
