Find dimensionless groups from the variables involved in force, $F$ exerted on the body and the given variables.

Given that:

The force, $F$ is a function of:

Velocity, $v$

Density, $$

$,$ Viscosity, $$

body distance, $x$

Evaluate:

The dimensionless groups

Ans check: or $[$:$\frac{x^2{v}^2}{F}=f(\frac{}{vD})\}$
