Subtopic: Calculation of performance parameters – field capacity, efficiency, performance index, application rate and losses
Question Statement:
Theoretical field capacity ($TFC$) of a farm implement depends strictly on which two operational parameters?
Options:
(A) Rated cutting width and forward travel speed
(B) Actual cutting width and turning time at headlands
(C) Tractor engine power and soil penetration resistance
(D) Wheel slip and fuel consumption rate
Answer Key:
A
Step-by-Step Solution & Explanation
- **Theoretical Field Capacity ($TFC$):** The rate of field coverage that would be obtained if the machine were performing its function $100\%$ of the time at rated forward speed and utilizing $100\%$ of its rated rated width.
$TFC = \frac{W \times S}{10} \text{ (ha/h)}$
where $W$ is rated implement width in meters and $S$ is forward speed in $\text{km/h}$.
