REDWOOD VISCOMETER NO. 1
To determine the kinematic viscosity and absolute viscosity of the given thin sample of oil at various temperatures and to study the variations of viscosities with temperature using Redwood viscometer No. 1.
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. 1, two thermometers (0–100°C), a narrow-necked flask (50 cc), a stop watch.
It is a silver plated brass ...
