Pressure Unit Information
Pressure is the force applied perpendicular to the surface of an object per unit area. It is commonly measured in Pascals (Pa), but various units such as atmospheres (atm), bars, and psi (pounds per square inch) are also used in different fields.
Common Pressure Units and Their Relationships:
- 1 Pascal (Pa) = 1 N/m²
- 1 Kilopascal (kPa) = 1,000 Pa
- 1 Megapascal (MPa) = 1,000,000 Pa
- 1 Atmosphere (atm) = 101,325 Pa
- 1 Bar = 100,000 Pa
- 1 Torr (mmHg) = 133.322 Pa
- 1 Pound per Square Inch (psi) = 6,894.76 Pa
- 1 Millibar (mbar) = 100 Pa
Applications of Pressure Measurements:
- Weather Forecasting: Atmospheric pressure is measured in millibars (mbar) to predict weather changes.
- Engineering: Pascal (Pa) and Megapascal (MPa) are used in stress analysis and structural engineering.
- Fluid Mechanics: Bar and Torr are commonly used in hydraulic and pneumatic systems.
- Diving & Aviation: Pressure gauges in psi and atm are essential for scuba diving and aircraft cabin pressure regulation.
Formula for Pressure Calculation:
Pressure (P) is defined as force (F) per unit area (A):
P = F / A
Where:
- P = Pressure (Pa)
- F = Force (N - Newtons)
- A = Area (m²)
Example Calculation:
If a force of 500 N is applied to an area of 2 m², the pressure exerted is:
P = 500 N / 2 m² = 250 Pa
