Engineering Properties of Agriculture Produce

• Sphericity, φ = (surface area of a sphere having the same volume as the particle) / (actual surface area of the particle). • Cube volume = L³. Equivalent-volume sphere diameter de: (π/6)de³ = L³ ⇒ de = L(6/π)^(1/3). • Sphere surface area = πde² = πL²(6/π)^(2/3). Cube surface area = 6L². • φ = π(6/π)^(2/3)/6. Numerically, (6/π)=1.9099, raised to 2/3 ≈ 1.539; φ = π×1.539/6 ≈ 4.834/6 ≈ 0.806, inside the accepted range 0.707–0.807.
