How do I explain this problem? Centripetal/Centrifugal force!

Basically to answer the question below, I am trying to say that the water droplets move outward to the edges of the drum for whatever reason and once they pass through the holes they fly off tangentially to the drum. But I'm having difficulty finding the correct blend of words...

"What is the purpose of a spin cycle of a washing machine? Explain in terms of acceleration components."

The purpose of a spin cycle of a washing machine is to remove water from clothes.

The drum of radius, r, rotating with speed, v, will have a centripetal acceleration $a_{cp} = \frac{v^2}{r}$ which is provided by a centripetal force, acting toward the centre of the drum, which in turn has an equal and opposite reaction (centrifugal?) force.

The Inertia of the clothes and the water particles encourages them to keep them moving in a straight line, that with the combination of the reaction force, causes them to move around the edge of the drum and the water particles move out through the holes in the drum, which then fly off at a tangent to the drum's rotation.

Is there anything wrong with what I have said? How can I word it better?

Centrifugal force is imaginary. Instead, the water droplets perceive gravity in the opposite direction to the centripetal force and so are inclined to move outwards, away from the centre of the drum.

I probably have not explained that very well but I found that this lecture was very useful in explaining circular motion. I highly recommend it if you have time to watch it:

Yes but the equal and opposite reaction force to the centripetal force is not imaginary and is sometimes referred to as the 'reactive centrifugal force' which is why I put a question mark next to centrifugal force.

And thanks for the link.

The reaction forces of the clothes on the drum would simply be called 'reaction forces'

Centrifugal force is a funny thing.. To say it "doesn't exist" is a little wrong.

Without too much detail; Centrifugal forces 'appear' to be real in non-inertial reference frames. For instance, imagine you are in a car, with something on the dashboard. Going around the roundabout, the something slides to the left hand side of the dash. In the reference frame of the car, some force pushed that something and did work on it, while the centripetal force was working on the whole frame. This is an example of a fictitious force, one that doesn't actually exist (since it's not observable in all reference frames) but can still do work in some. The reason why it's a little wrong to say it doesn't exist is because it turns out gravity is in fact, a fictitious force; yet we all know how real that is.
