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. Press Calculate to find NH3/hr. flow rate.
Enter only numeric values (no commas), using decimal points where needed. Non-numeric values will cause errors.
