Common Equations
| * GPM (gallons/minute) | = | GPA x MPH x Width (feet) 495 |
| Acres | = | DISTANCE (ft) x WIDTH (feet) 43,560 |
| Flowmeter Cal # | = | GALLONS (monitor) x FLOWMETER CAL # (current) ACTUAL GALLONS |
NH3 Equations
| NH3/hr. | = | NPA x MPH x WIDTH (feet) x .1212 .82 |
| NH3/min. | = | NPA x MPH x WIDTH (feet) ÷ 495 .82 |
NH3/HR. Calculator
Use this calculator to determine NH3/hr. flow rate.
- Enter – Application Rate – NPA (lbs. Nitrogen / Acre)
- Enter – Ground Speed – MPH
- Enter – Implement Width – Width in feet
- See Result to find NH3/hr. flow rate.
Enter only numeric values (no commas), using decimal points where needed. Non-numeric values will cause errors.
