Vacuum Leak Rate Calculator

This calculator estimates the vacuum leak rate based on the pressure drop over time in a vacuum system.

Input Parameters

Calculation Formula

Leak Rate (sccm) = (P1 - P2) / t

Where:
P1 = Initial Pressure (Pa)
P2 = Final Pressure (Pa)
t = Time (seconds)
sccm = standard cubic centimeters per minute

Vacuum Leak Rate Calculator Usage Guide

Learn how to use the Vacuum Leak Rate Calculator and its working principles

How to Use the Calculator

  1. Enter the initial pressure of the vacuum system in Pascals (Pa).
  2. Enter the final pressure of the vacuum system in Pascals (Pa).
  3. Enter the time duration in seconds over which the pressure drop was measured.
  4. Click the "Calculate" button to compute the leak rate in standard cubic centimeters per minute (sccm).
  5. The result will be displayed in the "Leak Rate (sccm)" field.

Understanding the Formula

The calculator uses the formula:

Leak Rate (sccm) = (P1 - P2) / t

Where:

  • P1 = Initial Pressure (Pa)
  • P2 = Final Pressure (Pa)
  • t = Time (seconds)

This formula estimates the leak rate by calculating the average rate of pressure change over the given time period.
