mesh grade / sizing

I may be wrong but I think the mesh is defined by the size of the holes not by the number of holes in a given area.

I think you're right, based on the size of particles that pass through

-or don't.

OK so on that basis if I assume the material used is approx the same thickness as the holes created then that would be:

P.S. The mesh is used to create a foam as a water/detergent mix passes through.

A couple of sources which may help:

Do you know that it will work? I ask because normally you need a lot of aeration to get a decent foam, which in turn requires energy. Think of whisking egg white to make meringue; it's quite hard work. Industrial froth flotation units for separating minerals usually have pretty hefty motors driving aerating impellers to create the foam. Simply passing soapy water through a screen won't necessarily do the job.

It should work as I am taking the dimensions from an existing item, it is actually a carpet cleaning system, that produses foam to surface clean the carpet and the `mesh module` is broken. I cant find spares for it so attempting to make something.
