The purpose of this experiment is to determine the viscosity with varying temperature of the liquids. A redwood viscometer is used to measure the flow of eight different liquids including engine oil, sunflower oil, soybean oil, glycerol, thermic fluid (Hy- therm), coconut oil, water and ghee.

How does a redwood viscometer work?

The redwood viscometer consist of vertical cylindrical oil cup with an orifice in the centre of its base . ... A hook pointing upward serve as a guide mark for filling the oil . The cylindrical cup is surrounded by the water bath . The water bath maintain the temperature of the oil to be tested at constant temperature .

What is the use of redwood viscometer?

Redwood Viscometer is used for the determination of redwood viscosity and which can be converted to Kinematic viscosity also. It is also used for observing the effect of temperature on viscosity by plotting graph.
