Deduce the formula of Reynolds number in the form of inertial force and viscous force .

Explanation

Reynolds number `R_(e)=(rhov^(2))/(((etav)/d))`
Multiplying and dividing by A to right side equation,
`R_(e)=(rhoAv^(2))/(((etaAv)/(d)))`
`R_(e) = ("Inertial force")/("Viscous force")`
Thus `(R_(e)` represets the ratio of inertial force, that is force due to mass of moving fluid or due to inertia of obstable in its path to viscous force)
Hence `R_(e)` represents the ratio of inertial force of to viscous force.
