The applicability of proposed correlations for the calibration of a rolling ball viscometer in the intermediate Reynolds number region (0.3 < Re 1000) has been studied. The constants for the equation correlating ball roll time with viscosity have been derived and compared with their experimental values. The dependency of these constants on temperature and on the dimensions of the viscometer has also been described which may help in the optimal design of a rolling ball viscometer.
