Neco Model Questions Vol1 2024 Agricultural Science Question 30
Practice objective / multiple choice question 30 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
A farmer wishes to pull a mouldboard plough with a width of 0.25 m to a tillage depth of 0.20 m. The soil draft coefficient is \(12\,000\) N·s m\(^{-3}\), and the soil condition factor is 1.3. The tractor's drawbar pull efficiency is 0.85, and the intended travelling speed is 5 km h\(^{-1}\). Using the draft formula \(D = K \times w \times d \times n\) and the power relation \(P = \frac{D \times v}{\eta}\), calculate the minimum tractor power required (in kW), rounding to one decimal place.
