Question Statement:
A self-propelled reaper has a cutter bar width $W = 1.2\text{ m}$ and travels forward at speed $S = 3.0\text{ km/h}$. If field efficiency is $\eta = 80\%$, the effective field capacity $EFC = \frac{W \times S}{10} \times \eta = \frac{1.2 \times 3.0}{10} \times 0.80$ in ha/h is (rounded off to three decimal places):
