From measurements on a uniformly sized material from a dryer, it was found that the surface area of the material is 1200 m2. If the density of the material is 1450 kg m-3 and the total weight is 360 kg calculate the equivalent diameter of the particles.

Answer:

[tex]D = 2.07\times 10^{-4} m[/tex]

Explanation:

We know that the volume of the material

= mass/density

mass= 360 Kg

density = 1450 kg/m^3

Volume= 360/1450= 0.248 m^3

and Volume = Area× equivalent Diameter

Area= 1200 m^2

⇒Equivalent Diameter= Volume/Area= 0.248/1200=

[tex]D = 2.07\times 10^{-4} m[/tex]
