This air passes from the solid particles at a velocity adequately higher to suspend the stable in a completely fluidized condition.
Contrary to the weight and standard force, which happen to be envisioned to act with the idea on the arrow, the friction power can be a sliding vector and therefore the point of application is not really relevant, plus the friction acts together The full foundation.
