A bulk grain shows a marked increase in its angle of repose after prolonged handling. Which operational inference is most justified?
Correct answer: C
A larger angle of repose generally indicates greater interparticle friction/cohesion and poorer gravity flow; it does not uniquely establish density or moisture changes.
A grain has a bulk density of 750 kg/m³ and a true particle density of 1,250 kg/m³. Its approximate intergranular porosity is:
Correct answer: B
Porosity = 1 − bulk density/true density = 1 − 750/1250 = 0.40, or 40%.
A 1,200 kg grain lot at 15% moisture (wet basis) is dried to 12% (wet basis), with dry matter conserved. The approximate mass of water removed is:
Correct answer: D
Dry matter = 1200 × 0.85 = 1020 kg. Final lot mass = 1020/0.88 = 1159.09 kg; water removed ≈ 40.91 kg.
