83 gtt/min. Using the formula (Volume × Drop factor) divided by Time in minutes: (2000 × 60) divided by 1440 minutes = 120000 divided by 1440 = 83.33, which rounds to 83 gtt/min. With microdrip (60 gtt/mL), the drip rate equals the mL/hr rate numerically: 2000 divided by 24 = 83.33 mL/hr = 83 gtt/min.
