. In the manufacture of coated wires the wire is pulled through a bath of coating liquid and then through a die which "wipes" the liquid and leaves a coating of desired thickness. It is required to relate the ultimate radius of the coated wire, Rc, to the radius of the uncoated wire, Rw, and the die radius, Rd. The wire moves with velocity Vw and the die length L is assumed to be long enough to ignore entrance effects. Ra... T Bath of coating liquid Rw die 1 RC J Vw L-
