Subtopic: Particle size analysis for comminuted solids

Question Statement:

For a ground feed sample, the Fineness Modulus is determined from standard ASAE sieve analysis as $FM = 3.5$. Using the Henderson formula for average particle diameter $D = 0.0041 \times (2)^{FM}\text{ inches}$, the average diameter $D$ (in inches, rounded to 3 decimal places) is:

Answer Key:

0.046

Step-by-Step Solution & Explanation

$D = 0.0041 \times 2^{3.5} = 0.0041 \times 11.3137 = 0.046\text{ inches}$
