- Click the “Calculate” button to obtain the vacuum pressure result.
Formula:
The formula for calculating vacuum pressure (Pvac) is given by:
Where:
- Pvac is the vacuum pressure.
- Patm is the atmospheric pressure.
- Pabs is the absolute pressure.
Example Solve:
Let’s consider an example. If the atmospheric pressure is 101.325 kPa and the absolute pressure is 90.5 kPa, the vacuum pressure can be calculated as follows:
Thus, the vacuum pressure is 10.825 kPa.
FAQs:
Q1: What units should I use for pressure inputs?
A1: Ensure consistency; use the same units for atmospheric and absolute pressures, such as kPa or psi.
Q2: Can the calculator handle negative results?
A2: Yes, a negative result indicates a pressure lower than atmospheric, representing a vacuum.
Q3: Is this calculator suitable for high-pressure systems?
A3: Yes, the calculator accommodates various pressure ranges, but ensure consistent units.
