Hi.(adsbygoogle = window.adsbygoogle || []).push({});

I am reading this chapter about dimensionless ratios and scaling law. and it says like this:

[itex]\alpha[/itex]F = [itex]\frac{Fp}{Fm}[/itex] = [itex]\frac{ρp . Vp^2 . Lp^2}{ρm . Vm^2 . Lm^2}[/itex] (1)

From this, it is obvious one can write for these forces:

Fp = C[itex]\frac{1}{2}[/itex] [itex]ρp Vp^2 . Lp^2[/itex] (2) and

Fp = C[itex]\frac{1}{2}[/itex] [itex]ρm Vm^2 . Lm^2[/itex] (3)

The thing I don't understand is, how can from equation (1) to equation (2) and (3)..
