Enter the effluent flow and the blood rate flow into the Calculator. The calculator will evaluate the Flow Fraction.

## Flow Fraction Formula

FF = EF / BRF

Variables:

- FF is the Flow Fraction ()
- EF is the effluent flow
- BRF is the blood rate flow

To calculate Flow Fraction, divide the effluent flow by the blood rate flow.

## How to Calculate Flow Fraction?

The following steps outline how to calculate the Flow Fraction.

- First, determine the effluent flow.
- Next, determine the blood rate flow.
- Next, gather the formula from above = FF = EF / BRF.
- Finally, calculate the Flow Fraction.
- 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.

effluent flow = 430

blood rate flow = 300
