Question

Which among the following is not the correct symbol?

(a) Size- l

(b) Velocity – v

(c) Gravity – g

(d) Viscosity – a

I had been asked this question during an online interview.

I want to ask this question from Rayleighs Method topic in section Dimensional and Model Analysis of Fluid Mechanics

Answer 1

Correct answer is (d) Viscosity – a

Explanation: The symbol used for viscosity is false. Viscosity is denoted by the symbol ‘µ’ (Mew). It is defined as the resistance to flow of fluid. Resistance takes place as one layer of fluid slides over the other.
