Question

Which of the following is not a viscometers​

Answer 1

Complete question:

Which of the following is not a viscometers

A. Capillary

B. Falling Sphere

C. Rotational

D. Drop weight

D. Drop weight is not a viscometers.

Viscometer:

• A viscometer is a device that measures the viscosity of a fluid.
• A rheometer is used to measure the viscosity of liquids whose viscosity varies with flow conditions.
• As a result, a rheometer can be thought of as a subset of a viscometer.
• Viscometers can only measure in a single flow condition.
• Viscometers are classified into three types:

1. Capillary tube (e.g., Ostwald)
2. Coaxial cylinder (e.g., Brookfield, Couette)
3. Falling sphere (e.g., Hoeppler)

• An advanced controlled pressure rheometer, such as a Carrimed or Bohlin, could be used for research.

Hence drop weight is not a viscometers.
