(a)What mesh and corresponding wire diameter would be required to achieve 80% conversion?
(b)For the same mesh size, how many screens would be necessary to achieve 80% conversion?
(c) Repeat part (b) for 99.9% conversion.
(d) If the mesh size and wire diameter could be varied independently, which would bring about a greater increase in conversion, doubling the mesh size or halving the wire diameter?
