How do I calculate making a dust devil by spinning

[TheAngryOrange]

You have an instance where someone takes an axe then begins spinning place really really fast and a dust devil or some sort of vortex of air forms large enough and strong enough it looks like a small tornado.

How do I calculate that?

No, it took place in a desert arena area. Nothing but sand.

Maybe you can use RKE (Rotational Kinetic Energy) if the feat is like a tornado, but that requires you to find the sand mass first.
