Calculate Leak Rate





Formula

To calculate the Leak Rate (LR):

\[ LR = \frac{V \times \Delta P}{\Delta t} \]

Where:

What is a Leak Rate?

A leak rate is defined as the rate of flow, or “leak”, of gas out of a container that is attempting to hold the gas. This can be determined using the ideal gas law and is typically measured in units of flow rate such as ft-lbf/sec.

Example Calculation

Let's assume the following values:

Using the formula:

\[ LR = \frac{10 \times 200}{60} = \frac{2000}{60} = 33.333333 \text{ ft-lbf/sec} \]

The Leak Rate is 33.333333 ft-lbf/sec.
