Calculate Boil Off Rate (BOR)





Formula

The formula to calculate the Boil Off Rate (BOR) is:

\[ BOR = \frac{V1 - V2}{T} \]

Where:

Example

Let's say the volume before boil (\( V1 \)) is 1000 mL, the volume after boil (\( V2 \)) is 800 mL, and the time of boil (\( T \)) is 30 minutes. Using the formula:

\[ BOR = \frac{1000 - 800}{30} \]

We get:

\[ BOR = \frac{200}{30} \approx 6.67 \text{ mL/min} \]

So, the Boil Off Rate (\( BOR \)) is approximately 6.67 mL/min.

What is Boil Off Rate?

The Boil Off Rate (BOR) is a measure of the volume of liquid that evaporates during boiling over a specific period of time. It is commonly used in brewing, cooking, and various industrial processes to understand and control the evaporation rate of liquids.
