## FAQs

**How do you calculate sprayer rate?**The sprayer rate is calculated by dividing the amount of pesticide or liquid chemical needed by the area you want to cover. It is typically expressed in gallons per acre (GPA) and can be calculated using the formula: Sprayer Rate (GPA) = Amount of Chemical (Gallons) / Area (Acres).**How do you calculate GPM for a sprayer?**To calculate the Gallons Per Minute (GPM) for a sprayer, you can use the formula: GPM = Sprayer Rate (GPA) × Speed (MPH) / 5940. This formula assumes that the width of the spray swath is 20 feet.**How do you calculate spray nozzle?**Spray nozzle size is determined by the desired flow rate (GPM) and pressure (PSI) for your specific application.
