their SI units? What are their typical values for air and water at atmospheric conditions?
(b) What is specific gravity? What are the values of specific gravity for (i) water, (ii)
mercury?
(c) What is rate of strain and what are its SI units?
(d) One can tell a raw egg from a boiled one by spinning it on a table. A boiled egg spins
for a longer time. Explain using fluid mechanics concept. (Assume negligible difference
in moment of inertia).
