A tractor-mounted boom sprayer carries a horizontal row of 12 identical flat-fan nozzles (spray angle 110°). To achieve uniform coverage, the required lateral overlap between adjacent nozzle footprints at the target plane is 30% of single nozzle footprint. Boom height is 0.60 m above the target plane.
The tractor is set to travel at a theoretical forward speed of 8 km.h−1. Wheel slip is 8% and the field efficiency is 75%. All other losses are neglected. The total time (in minutes) required to spray 25 ha field is ________. (Rounded off to the nearest integer)
