Question Statement:
A screw conveyor has screw diameter $D = 0.3\text{ m}$, shaft diameter $d = 0.1\text{ m}$ \approx 0.06283\text{ m}^2$). Pitch $P = 0.3\text{ m}$, speed $N = 60\text{ rpm}$, and loading factor $\phi = 0.30$. The theoretical volume conveyed in 1 hour in $\text{m}^3/\text{h}$ is (rounded off to one decimal place):
Step-by-Step Solution & Explanation
$Q = 60 \times 0.0628318 \times 0.3 \times 60 \times 0.30 = 20.356\text{ m}^3/\text{h} \approx 20.4\text{ m}^3/\text{h}$.
