Additional Homework Problems

CDP14-BB

  Currently, 35% conversion is achieved in a 20-mesh gauze screen with a 0.51-mm wire diameter.
     
   

(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?
