The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of thickness. For example, Syrup has a higher viscosity than water. Viscosity can be conceptualized as quantifying the frictional force that arises between adjacent layers of fluid that are in relative motion.
Expect for the year of 2015 and 2013, no question has been asked from this chapter in the other years. The last 4 years have had a drought for the questions from this chapter. Hence, we should not be expecting any question from this chapter in the upcoming paper.
The below given graph will illustrate the above-mentioned analysis:
The important topics to be covered from this chapter are:
• Stokes Law
• Terminal Velocity
• Streamline and Turbulent Flow
• Critical Velocity
• Bernoulli’s Theorem and its applications
Tips and Tricks:
• NCERT will form the base for the understanding of further queries and it provides a stern platform to further work on. Here is the NCERT PDF version of the chapter:
• There are various flow charts in this chapter. Hence, they must be created in a single large sheet of paper and looked upon at regular intervals.
• There is a huge number of unique terms and keywords. Hence, they must be revised regularly. Once in a fortnight is a must.
• The diagrams must be practiced and understood clearly. Video explanations can be looked onto if one finds difficulty in understanding the diagram.
