Question

In Red Wood Viscometer

• A. Absolute value of viscosity is determined
• B. Part of the head of fluid is utilised in overcoming friction
• C. Fluid discharges through orifice with negligible velocity
• D. Comparison of viscosity is done

Answer 1

Answer:

A. Absolute value of viscosity is determined

Redwood viscometer determines the absolute value of viscosity by measuring the time taken for a fixed volume of fluid to flow through an orifice at a specific temperature. The frictional force between the fluid and the orifice determines the viscosity.
