Thanks @Avinash.

Free convection is a function of (g, L, mu, cp, rho, k) and forced is a function of (Velocity, L, mu, cp, rho, k).

Is it right? Anyone agree with this answer?

Yes the free convection is governed by grashof's number.

And the above formula is for grashof's no: {g*(BETA)*(temperature difference)*L^3}/nu^2.

bgTL^3/(nu)^2.
