(a) What are the typical symbols used for the dynamic and kinematic viscosity? What are

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).

(e) What is a Reynolds number? What are its units?
