The present invention relates to an apparatus and method for determining the viscosity of Newtonian and non- Newtonian fluids. More particularly, the present invention relates to an apparatus and method for determining the viscosity of a fluid by measuring the time of fall of a needle through a predetermined distance of the fluid held in a container. The method further provides exact equations according to a modified power law model and Ellis model for the calculation of viscosity, shear stress and shear rate.
