## Residence Time Formula

The following two example problems outline the steps and information needed to calculate the Residence Time.

RT = V / Q

Variables:

- RT is the Residence Time (min)
- V is the reactor volume (mL)
- Q is the flow rate (mL/min)

To calculate residence time, divide the reaction volume by the flow rate.

## How to Calculate Residence Time?

The following steps outline how to calculate the Residence Time.

- First, determine the reactor volume (mL).
- Next, determine the flow rate (mL/min).
- Next, gather the formula from above = RT = V / Q.
- Finally, calculate the Residence Time.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

reactor volume (mL) = 567

flow rate (mL/min) = 30

RT = V / Q** **= ?
