Question
A 9-row seed cum fertilizer drill operated at forward
speed of 5 km/hr with field efficiency of 80% having row spacing of 200 mm will have effective filed capacity isSolution
Forward speed: 5 km/hr Field efficiency: 80% Row spacing: 200 mm Forward speed = 5 km/hr = 5,000 meters / 60 minutes = 83.33 meters/min Working width = 9 rows x 200 mm = 1,800 mm = 1.8 meters Effective field capacity = (Working width x Forward speed x 10) / Field efficiency = (1.8 meters x 83.33 meters/min x 10) / 0.80 = 2249.92 square meters per minute To convert the field capacity from square meters per minute to hectares per hour: Effective field capacity = 2249.92 square meters/minute x (60 minutes/10,000 square meters) Effective field capacity = 1.35 hectares per hour Therefore, the effective field capacity of the 9-row seed cum fertilizer drill operated at a forward speed of 5 km/hr with a field efficiency of 80% and a row spacing of 200 mm is approximately 1.35 hectares per hour.
