Dear Mr. Teus,

With your permission, I dare to ask you about something that is still not clear to me.

And this is about "Solid Loss Factor".

Is this related to the slip of the product ? If this is the case, should be related to the floating/saltation velocity.

Or it is related to the friction coefficient of the product ?

Some more clarifications from you are very welcome. 

Thank you for all your support.

Sincerely yours,

Tanase TANASE
