The force, or torque, required to turn the probe is used to determine viscosity. The probe in the liquid sample will be rotated by these instruments.
The intermolecular friction that occurs when layers of fluids attempt to glide over each other can cause shear stress in the fluid.Ī rotational viscometer is a useful tool for determining dynamic viscosity. The viscosity of a fluid is a measurement of its resistance to progressive deformation under tensile or shear stress. Also, when it comes into touch with solid limits, how it will move.
The viscosity of a fluid is a crucial attribute to know in order to understand its behavior. Role of Mahatma Gandhi in Freedom Struggle.
