Which of the following properties are considered aerodynamic properties of agricultural seeds?
Options:
(A) Terminal velocity ($V_t$)
(B) Drag coefficient ($C_d$)
(C) Projected frontal area
(D) Modulus of elasticity ($E$)
Answer Key:
A, B, C
Step-by-Step Solution & Explanation
Aerodynamic properties govern the behavior of particles in air streams (pneumatic conveyance, winnowing, air-screen cleaners). Key properties include terminal velocity, drag coefficient, and projected area perpendicular to air flow. Modulus of elasticity is a mechanical/rheological property.
