Fill-in-the-blank: When determining the dynamic viscosity of a sample, an appropriate viscometer should be selected based on the sample’s temperature, ensuring that the flow time of the sample is not less than ( ) seconds. 200
The flow time of the sample should be no less than 200 s
For 200s models, the flow time of a viscometer with an inner diameter of 0.4 mm should be at least 350s.
When measuring the kinematic viscosity of a sample, an appropriate viscometer should be selected based on the sample’s temperature, ensuring that the flow time of the sample is not less than (200) seconds.
