Powder Metallurgy Exercise
1. A screen with 325 mesh count has wires with a diameter of 0.001377 in. Using Eq. (16.1), determine: (a) the maximum particle size that will pass through the wire mesh, and (b) the proportion of open space in the screen.
2. A screen with 10 mesh count has wires with a diameter of 0.0213 in. Using Eq. (16.1), determine: (a) the maximum particle size that will pass through the wire mesh, and (b) the proportion of open space in the screen.
3. What is the aspect ratio of a cubic particle shape.
