Subtopic: Particle size analysis for comminuted solids
Question Statement:
In a Tyler standard sieve series, the ratio of the mesh aperture dimension of any given sieve to that of the immediately preceding smaller sieve in the standard series is:
Options:
(A) $\sqrt{2} \approx 1.414$
(B) $\sqrt[4]{2} \approx 1.189$
(C) $2.0$
(D) $\sqrt{3} \approx 1.732$
Answer Key:
A
Step-by-Step Solution & Explanation
The Tyler standard sieve series is based on a 200-mesh wire cloth with an opening of $0.074\text{ mm}$, where consecutive aperture widths increase in the geometric ratio of $\sqrt{2} \approx 1.414$ (or $\sqrt[4]{2}$ for the extended double series).
