Abstract
A locally constructed simple capillary viscometer was used to study the variation of viscosity of various volumes of petrol added to a fixed volume of kerosene. The density and viscosity of petrol-kerosene mixtures decreased with increasing petrol concentration in a fixed amount of kerosene. The study revealed that estimation of petrol concentration in petrol-kerosene mixture was much easier and better done by using calibrated curve of viscosity-petrol concentration than density-petrol concentration.
