Material Handling and Storage

A screw conveyor has conveying annular area $A = 0.05\text{ m}^2$, pitch $s = 0.25\text{ m}$, rotational speed $N = 120\text{ rpm} = 2.0\text{ rev/s}$, and trough loading loading factor $\psi = 0.40$. The volumetric capacity $Q_v = A \times s \times N \times \psi = 0.05 \times 0.25 \times 2.0 \times 0.40$ in $\text{m}^3/\text{s}$ is:
