In deep bed grain drying, the thickness of the active drying zone depends on airflow rate. For an airflow rate of $Q = 0.4\text{ m}^3/\text{s}$ through a bin floor of area $A = 8.0\text{ m}^2$, the superficial air velocity $v_s = Q / A$ in m/s is:

Answer Key:

0.05

Step-by-Step Solution & Explanation

$v_s = 0.4 / 8.0 = 0.05\text{ m/s}$.
