Analysis of a flow phenomenon in a system requires the following variables:

Pressure [M L-1 T ^{-2}]

Velocity of the fluid [L T ^{-1}]

Size of the system [L]

Density of the fluid [M L^{-3}]

Viscosity of the fluid [M L^{-1} T ^{-1}]

According to Buckingham Pi theorem (dimensional analysis) what is the number of independent DIMENSIONLESS variables needed to describe this system?

(A) 2 (B) 3 (C) 4 (D) 5

Option A - 2 independent variables is correct

Option A – 2 independent variables is correct

See lessCorrect answer is option A. Number of independent dimensionless variables= Total number of given variables- Total number of given units i.e 5-3= 2.

Correct answer is option A.
