How do you calculate GTTS per minute?

To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is… total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.
Considering this, how do I calculate flow rate?
The flow rate formula, in general, is Q = A × v, where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point.
Consequently, how many drops is 100 mL per hour?

IV Tubing Drop Factor | Desired Hourly Rate: ML / HR | |
20 | 100 | |
---|---|---|
10 DROP/ML | 3 | 16 |
15 DROP/ML | 5 | 25 |
20 DROP/ML | 6 | 32 |
There are a number of different drip factors available in clinical practice, however the commonest are: 10 drops per ml (blood set). 15 drops per ml (regular set). 60 drops per ml (burette, microdrop).
