Analysis of a flow phenomenon in a system requires the following variables:
i. Pressure [ M L-1T-2]
ii. Velocity of the fluid [L T-1]
iii. Size of the system [L]
iv. Density of the fluid [M L-3]
v. Viscosity of the fluid [M L-1T-1]
According to Buckingham Pi theorem (dimensional analysis) what is the number of independent DIMENSIONLESS variables needed to describe this system?
