Abstract
Tracker-aided experiments using communicating vessels have been performed to determine the viscositycoefficients of liquids at room temperature with weighted linear regression analysis. The calculation involves weightedlinear regression analysis of ln[(2z1/z0) 1] against time, where z1 and z0 are the instantaneous liquid level andthe initial liquid level in one of the vessels with the higher initial liquid level, respectively, and a computer-aided 2goodness of fit test. Based on the maximum Reynolds number obtained, it is concluded that the liquid flow was laminar,as required by the theory. From the 2 goodness of fit test it is concluded that the relation between ln[(2z1/z0) 1]and time is linear, in agreement with theory. As samples, water and rectified spirit were used. The viscosity coefficientsof both liquids obtained from experiments using various capillary tube sizes agreed with accepted values.
