What does a Brookfield viscometer measure?
What does a Brookfield viscometer measure?
The Brookfield Dial Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a fluid’s resistance to flow.
Which type of viscometer Brookfield is?
Brookfield viscometers employ the well-known principle of rotational viscometry; they measure viscosity by sensing the torque required to rotate a spindle at constant speed while immersed in the sample fluid.
What is the principle of Brookfield viscometer?
Classical Brookfield viscometers employ the principle of rotational viscometry – the torque required to turn an object, such as a spindle, in a fluid indicates the viscosity of the fluid.
How do you test Brookfield viscosity?
A sample of 400 – 600ml in a suitable container is placed under the viscometer which is then lowered to dip the spindle into the sample up to an immersion mark on the spindle shaft. The dip-in spindle is suitable for comparative testing of the viscosity of free-flowing fluids.
What is the use of viscometer?
A viscometer is an instrument used to measure fluid viscosity and the flow properties of liquids. Let’s discuss the various styles of viscometers, their internal characteristics and factors that go into performing a precise and repeatable viscosity measurement.
What is the dimensional formula of viscosity?
Or, η = [M1 L1 T-2] × [M0 L2 T0]-1 × [M0 L1 T-1]-1 × [M0 L1 T0] = [M1 L-1 T-1]. Therefore, viscosity is dimensionally represented as [M1 L-1 T-1].
What is SI unit of viscosity coefficient N?
The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.
What are the factors that affects viscosity?
Viscosity is resistance to flow. For liquids, typically the larger the intermolecular forces (IMF) the higher the viscosity. The other factors that affect viscosity are temperature and the shape of the molecule.
Is there a low cost digital viscometer from Brookfield?

How to set the speed of rotation on a viscometer?
Sets the viscometer in either speed select or spindle select (see Table C1 in Appendix C) mode.When set in the left position, the operator may select speed of rotation. When set in the right position,the operator may select spindle.
