An Improvement of High-Pressure Rolling-Ball Viscometer and Evaluation of the Equipment Constant
Seiji SWAMURA
Abstract:Viscosity of water under high pressure is an important property to calibrate high-pressure viscometers. On the other hand, the high-pressure viscosity of water has to be measured using the high-pressure viscometers. In the present review, we show evaluation of an equipment constant under high pressure to measure the high-pressure viscosity of water, using our high-pressure rolling-ball viscometer as an example. Key Words:Viscosity, High pressure, Water, Rolling-ball viscometer
