Enter the total volume (mL), the time (mins), and the drops per mL into the Drip Rate Calculator. The calculator will evaluate the Drip Rate.

## Drip Rate Formula

The following formula is used to calculate the Drip Rate.

DRP = V/T * D
• Where DRP is the Drip Rate (drops/min)
• V is the total volume (mL)
• T is the time (mins)
• D is the drops per mL

To calculate the drip rate, divide the total volume by the time, then multiply by the drops per mL.

## How to Calculate Drip Rate?

The following two example problems outline the steps and information needed to calculate the Drip Rate.

Example Problem #1

1. First, determine the total volume (mL).
• The total volume (mL) is calculated to be : 500.
2. Next, determine the time (mins).
• The time (mins) is measured to be: 30.
3. Next, determine the drops per mL.
• The drops per mL is found to be: 6.
4. Finally, calculate the Drip Rate using the formula above:

DRP = V/T * D

The values provided above are inserted into the equation below and computed.

DRP = 500/30* 6 = 100 (drops/min)

Example Problem #2

The variables required for this problem are provided below:

total volume (mL) = 300

time (mins) = 10

drops per mL = 5
