The formula to convert inches of vacuum to psi (P) is:
\[ \text{P} = \left(\frac{\text{V}}{29.92}\right) \times 14.696 \]
Where:
Inches of vacuum is a unit of measurement used to quantify the level of vacuum pressure. It represents the difference between the atmospheric pressure and the pressure inside a vacuum system. A higher value in inches of vacuum indicates a stronger vacuum, meaning lower pressure inside the system compared to the atmospheric pressure. This measurement is commonly used in various applications, including HVAC systems, automotive engines, and laboratory equipment, to monitor and control vacuum conditions.
Let's assume the following value:
Using the formula:
\[ \text{P} = \left(\frac{20}{29.92}\right) \times 14.696 = 9.82 \text{ psi} \]
The Pressure (P) is 9.82 psi.
