Question

Why is it necessary to keep viscometer vertically mounted?

Answer 1

A viscometer (also called viscosimeter) is an instrument used to measure the .... Measuring the power input necessary to keep the oscillator vibrating at a constant amplitude.

Answer 2

Answer:

Explanation:

• A viscometer is a device used to gauge a fluid's viscosity (resistance to internal flow).
• One variation tracks the amount of time it takes a certain volume of fluid to pass through an aperture.
• The capillary tube viscometer measures the pressure required to induce a fluid to flow through a small tube at a specific rate.
• Other types rely on measurements of the time it takes for a sphere to pass through the fluid, the force required to rotate the inner cylinder of a coaxial pair (the fluid being tested fills the space between the two cylinders), or the speed at which oscillations of a disc vibrating in the fluid stop.
