Abstract
|
|
|
|
The viscosities of benzene have been determined at several temperatures and pressures to investigate the effect of temperature and pressure on the viscosity of benzene in liquid phase. When a falling ball viscometer with a constant volume contained a given amount of liquid benzene at desired temperatures and pressures, the viscosities of benzene in the viscometer could be evaluated from the measurements of the falling time of a skinker. The variations of the specific volume and the free volume of liquid benzene with temperature and pressure were, from the results, searched out. Finally, the effects of temperature and pressure on the viscosity of benzene were discussed by means of the variations of free volume with temperature and pressure.
