Flow Fraction Calculator

Formula

The formula to calculate the Flow Fraction (FF) is:

\[ FF = \frac{EF}{BRF} \]

Where:

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

What is Flow Fraction?

Flow Fraction (FF) is a measure used in medical and engineering fields to determine the ratio of effluent flow to blood rate flow. It helps in assessing the efficiency and effectiveness of various processes, such as dialysis, where maintaining the correct flow fraction is crucial for optimal performance.

Example Calculation

Let's assume the following values:

Effluent Flow (EF) = 200 mL/min
Blood Rate Flow (BRF) = 500 mL/min

Using the formula to calculate the Flow Fraction (FF):

\[ FF = \frac{EF}{BRF} = \frac{200}{500} = 0.4 \]

The Flow Fraction (FF) is 0.4.
