Hello,

How do I calculate tornado's kinetic energy, if known

1) velocity inside tornado
2) height
3) radius

I calculed it in following manner:

K=1/2(Iw^2)

w=V*R

I(cylinder, z)=1/2(MR^2), M=ro*Pi*R^2*h

K=1/4(ro*Pi*R^2*h)(V*R)^2

But sort of "not realy sure" that I can use rigid mechanics formulas in
case of air ...

Thanks in adwance for your reply.
