Calculate Purge Time





Formula

The formula to calculate the purge time is:

\[ \text{PT} = \frac{\pi \times D}{12} \times \frac{L}{PR} \times 60 \]

What is Purge Time?

Purge time refers to the time required to completely replace the air or any other gas inside a pipe with an inert gas or a new type of gas. This is important in various industrial processes to prevent contamination, oxidation, or explosions.

Example Calculation

Let's consider an example:

Using the formula to calculate the purge time:

\[ \text{PT} = \frac{\pi \times 10}{12} \times \frac{100}{200} \times 60 \approx 78.54 \text{ minutes} \]

This means that the purge time for this scenario is approximately 78.54 minutes.
