| Abstract: | In this paper,we provide a method which can be used to measure the viscosity coefficient of the liquid under high-pressure condition and low-boil substances using inclined tube,and measurement system was designed and constructed.The kinematic viscosity coefficients of pure water which is the standard substance to calibrate viscosity measurement system were measured to verify the accuracy and reliability of the experimental system.The measurement results show that the absolute average of relative deviations is 0.65%.Then the kinematic viscosity coefficients of the saturated liquid of the low-boil substance,R134a were also measured to detect the measurement system. |
