Common Equations

* GPM (gallons/minute) = GPA x MPH x Width (feet)
Acres = DISTANCE (ft) x WIDTH (feet)
Flowmeter Cal # = GALLONS (monitor) x FLOWMETER CAL # (current)

NH3 Equations

NPM (Nitrogen per Minute) = NPA x MPH x WIDTH (feet)
NH3/hr. = NPA x MPH x WIDTH (feet) x .1212 

NH3/HR. Calculator

Use this calculator to determine NH3/hr. flow rate.

  1. Enter – Application Rate – NPA (lbs. Nitrogen / Acre)
  2. Enter – Ground Speed – MPH
  3. Enter – Implement Width – Width in feet
  4. 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.
