Question

Which of the following type of viscometer is used for the measurement of viscosity of a Newtonian fluid:

• A. Cup and bob viscometer
• B. Brookfield's viscometer
• C. Pycnometer
• D. Ostwald viscometer

Hint:

For Newtonian fluids (fluids with constant viscosity), the Ostwald viscometer is commonly used in laboratory settings for accurate viscosity measurements.

Answer 1

The Correct Option is D

The Ostwald viscometer is used for the measurement of the viscosity of a Newtonian fluid. It works on the principle of measuring the time it takes for a fluid to flow through a narrow tube under the influence of gravity.
