mg=mv2gr, vg=√g.r
v>>vg
The body pushes against the outer wall of the tube and a reaction force from the wall pushes it towards the center of the circular path. It is this force on the body together with gravity that provides for the centripetal force.
Numerically,
Fw=Fb=mv2r−mgcos(θ)
where Fb and Fw are action and reaction pair. The vertical lift created by the reaction force on the tube wall by Fw is,
Fl=Fwcos(θ)=m{v2r−gcos(θ)}cos(θ)
The horizontal component that comes with this lift can be counter-balanced by another similar tube with the body rotating in the opposite sense. At high velocity v>>vg such that we can ignore the term mgcos2(θ), then
Fl=mv2rcos(θ)
If the body is a ferromagnetic fluid or mercury driven by a electromagnetic force, then it is possible to change its velocity v by changing the hollow radius of the tube or r the path of the tube, since velocity is inversely proportional to the radius squared,
vov=a2ao2
If
a2ao2=√cos(θ), then
v2=vo2{ao2a2}2=vo21cos(θ)
and so,
Fl=mv2rcos(θ)=mvo2r
which is a constant provided r is a constant, ie. a circular path. Fl can then be varied by changing vo. A pair of such a device that compensate each other laterally, will then generate a total lift of 2∗Fl. It is not possible to make the tube with a hollow radius of zero at θ=π2, but it can be at a practical minimum, af at some αf.
On the lower half of the tube,
mv2r=Fb−mgsin(α)
Fw=Fb=mv2r+mgsin(α)
When θ is measured from the vertical axis, then
θ=α+π2
sin(α)=sin(θ−π2)=sin(−(π2−θ))=−sin(π2−θ)=−cos(θ)
Still numerically,
Fw=mv2r−mgcos(θ) for π2<θ<π
This force is downwards, an expression for vertical lift is given by,
Fl=−Fwcos(θ)=mcos(θ){−v2r+gcos(θ)}
which is always negative given the value of r and θ. It is possible to change r with θ to obtain a path over which the body in motion inside is always experiencing a positive lift. In this case however we will bent the tube such that there is no lower half and at the same time provide for a tube that runs in the opposite sense to compensate for the horizontal component of Fw.

And we consider the whole tube filled with fluid in circular motion, then
ΔFl=Δmv2rcos(θ)
where Δm=ρ.πa2rΔθ and ρ, the density of the fluid.
Fl=2∫π/2αfρ.πa2rv2rcos(θ)dθ
Fl=2ρ.πa2v2∫π/2αfcos(θ)dθ
Fl=2ρ.πa2v2{1−sin(αf)}
Fl=2ρ.πa2v2 when αf=0
In the picture above, the device can then provide a constant lift of 6∗Fl at all time. Unfortunately, nobody can patent this but me.
In the case where v is varied, for a tube filled with fluid in circular motion, we let,
ao2a2=cos−1(θ), then since,
vov=a2ao2
v2=vo2{ao2a2}2=vo2cos−2(θ)
and so,
ΔFl=Δmv2rcos(θ)=Δmv2orcos−1(θ)
where Δm=ρ.πa2rΔθ and ρ, the density of the fluid.
Fl=2∫π/2αfρ.πa2rv2orcos−1(θ)dθ
Since a2=a2ocos(θ),
Fl=2ρ.πa2ov2o∫π/2αfdθ
Fl=2ρ.πa2ov2o{π2−αf}
Fl=ρ.π2a2ov2o when αf=0
It is not necessary to vary the hollow radius of the tube. However Fl independent of θ would mean that lift is uniform throughout the length of the tube.
If we do not ignore the effect of gravity, there is a negative term given by,
Fg=−2ρgπa2o∫π20rcos2(θ)dθ
When r is a constant ro
Fg=−2ρgπa2oro∫π20cos2(θ)dθ
Fg=−12ρgπ2a2oro
And the total lifts for the two cases are given by
Fl=2ρπa2ov2−12ρgπ2a2oro=ρπa2o(2v2−12gπro)
Fl=ρπ2a2ov2o−12ρgπ2a2oro=ρπ2a2o(v2o−12gro)
respectively.
