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.

Boil-Off Rate

Definition: This calculation helps determine the rate at which liquid evaporates during boiling.

Formula: \( \text{Boil-Off Rate} = \frac{\text{Initial Volume} - \text{Final Volume}}{\text{Time}} \)

Example: \( \text{Boil-Off Rate} = \frac{8 - 6.5}{1.5} \)

How to Calculate Boil Up Rate

Definition: This calculation helps determine the rate at which liquid boils up in a distillation column.

Formula: \( \text{Boil Up Rate} = \frac{\text{Vapor Flow Rate}}{\text{Column Cross-Sectional Area}} \)

Example: \( \text{Boil Up Rate} = \frac{500}{10} \)

CO2 Boil Off Rate

Definition: This calculation helps determine the rate at which CO2 boils off from a liquid.

Formula: \( \text{CO2 Boil Off Rate} = \frac{\text{Initial CO2 Volume} - \text{Final CO2 Volume}}{\text{Time}} \)

Example: \( \text{CO2 Boil Off Rate} = \frac{100 - 80}{2} \)

Liquid Nitrogen Boil-Off Rate Calculation

Definition: This calculation helps determine the rate at which liquid nitrogen boils off.

Formula: \( \text{Boil-Off Rate} = \frac{\text{Initial Volume} - \text{Final Volume}}{\text{Time}} \)

Example: \( \text{Boil-Off Rate} = \frac{50 - 45}{1} \)

Heat Needed to Boil Calculator

Definition: This calculation helps determine the amount of heat needed to boil a liquid.

Formula: \( Q = m \cdot c \cdot \Delta T \)

Example: \( Q = 2 \cdot 4.18 \cdot 80 \)

Boiler Flow Rate Calculator

Definition: This calculation helps determine the flow rate of a boiler.

Formula: \( \text{Flow Rate} = \frac{\text{Heat Output}}{\text{Temperature Rise} \times \text{Specific Heat Capacity}} \)

Example: \( \text{Flow Rate} = \frac{10000}{20 \times 4.18} \)
