Please answer completely and legibly.

Particle Technology

Problem:

Given the screen analysis below, calculate the following:

a.) sphericity

b.) specific surface area (mm2/g)

c.) number of particles per g

d.) volume-surface mean diameter (mm)

e.) arithmetic mean diameter

f.) mass mean diameter

g.) volume mean diameter

h.) number of particles per g of mesh 28/35 and

i.) the fraction of total number of particles for mesh 28/35

The value for the volume shape factor is 0.785 (cubic) with density of 3100 kg/m3.

Exclude particles collected in the pan.

 

I will upvote if the answer is complete and legible. Thanks
