Which factor is not part of the GPA determinants?

Which factor is not part of the GPA determinants?

• A. Temperature
• B. Flow rate per nozzle
• C. Application speed
• D. Effective sprayed width per nozzle

Answer: (D)

GPA (gallons per acre) is set by how much liquid is delivered and how much ground that liquid covers per unit area. The key factors are how much each nozzle dispenses per minute (flow rate), how fast you move across the field (application speed), and how wide the spray from each nozzle covers on the ground (effective sprayed width per nozzle). Temperature doesn’t enter the calculation; it can affect how droplets behave in the air (drift, evaporation, droplet size) but not the actual amount of product applied per acre. So the factor not part of GPA determinants is temperature.
