Which method can be used to determine the viscosity of gas?

The viscosity of a gas provides a means for determining molecular diameters, as viscosity arises from collisions among molecules. A gas sample is drawn through a thin capillary tube. The change in pressure of the system is measured with a manometer as a function of time.

What are the three ways to determine viscosity?

How do you determine viscosity?

There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.

Which instrument is used for the determination of viscosity?

viscometer viscometer, instrument for measuring the viscosity (resistance to internal flow) of a fluid.

Which method is most suitable for determining viscosity?

The capillary viscometer is one of the earliest known methods to determine fluid viscosity. This method measures the time taken for a defined volume of fluid to flow through a U-shaped capillary tube of known diameter and length.

How do you test for viscosity?

How does a viscosity measure viscometer?

The time required for the test liquid to flow through a capillary of a known diameter of a certain factor between two marked points is measured. By multiplying the time taken by the factor of the viscometer, the kinematic viscosity is obtained. Such viscometers can be classified as direct-flow or reverse-flow.

How do you measure viscosity without a viscometer?

Alternative viscometers only allow for single point measurement and provide only shear viscosity measures. Viscosity can also be measured by applying oscillating vibrations to the sample and monitoring the damping effects of the fluid.
