REDWOOD VISCOMETER NO. 2
To determine the kinematic viscosity and absolute viscosity of the given thick sample of oil (highly viscous) at various temperatures and to study the variations of viscosity with temperature by using Redwood viscometer No. 2.
Viscosity is the property of a liquid by virtue of which it offers resistance to its own flow. The viscosity of liquids decreases with increasing temperature. The rate at which the viscosity changes with temperature is known as viscosity index.
Redwood viscometer No. 2, two thermometers (0–100°C), a narrow-necked flask (50 cc), a stop watch.
It is a silver ...
