Question

What is the mathematical technique used to predict physical parameters?

(a) Combustion analysis

(b) Pressure analysis

(c) Dimensional analysis

(d) Temperature analysis

I have been asked this question in an interview.

My doubt is from Rayleighs Method in division Dimensional and Model Analysis of Fluid Mechanics

Answer 1

Right choice is (c) Dimensional analysis

The best explanation: Dimensional analysis is a process which is used to determine physical parameters that influence the fluid flow. The analysis is based on the fundamental units. The fundamental units are mass, length and time.
