Farm Machinery

Subtopic: Baler Mechanics

Question Statement:

A rectangular straw baler produces straw bales of dimensions $0.35\text{ m} \times 0.45\text{ m} \times 0.90\text{ m}$. If each bale weighs 20 kg, the baled straw bulk density in kg/m$^3$ is:

Answer Key:

141

Step-by-Step Solution & Explanation

Bale volume $V = 0.35 \times 0.45 \times 0.90 = 0.14175\text{ m}^3$. Density $\rho = \frac{20\text{ kg}}{0.14175\text{ m}^3} \approx 141.09\text{ kg/m}^3$.
