Pressure Is: Definition, Types
In the field of engineering and industrial systems, the concept of pressure is fundamental. From pipelines to hydraulic cylinders, understanding pressure is essential to ensure performance, safety, and efficiency.
What Is Pressure?
Pressure is the amount of force exerted on a surface per unit area. The basic formula is:
Pressure (P) = Force (F) / Area (A)
The SI unit for pressure is Pascal (Pa), where:
1 Pa = 1 Newton/m²
Common pressure units used in industrial applications include:
Bar
Psi (pound per square inch)
atm (atmosphere)
mmHg (millimeter of mercury)
Types of Pressure
Atmospheric Pressure
The pressure exerted by the Earth’s atmosphere.
1 atm = 101,325 Pa
Gauge Pressure
Measured using a pressure gauge; excludes atmospheric pressure.
Widely used in tanks and piping systems.
Absolute Pressure
Total pressure including atmospheric pressure.
Absolute = Gauge + Atmospheric Pressure
Differential Pressure
The difference between two pressure points.
Common in filtration, ventilation, and process control systems.
Industrial Applications of Pressure
| Application | Description |
|---|---|
| Industrial Piping Systems | Determines pipe wall thickness, valve strength, and flange selection |
| HVAC Systems | Controls airflow and efficiency of heating/cooling units |
| Hydraulic & Pneumatic Systems | Drives actuators and cylinders using controlled pressure |
| Pressure Tanks | Stores and regulates distribution of high-pressure fluids |
| Safety & Relief Valves | Prevents overpressure to avoid system damage or explosion |
Why Is Pressure Important?
Safety: Incorrect pressure calculations can lead to system failure or accidents.
Efficiency: Stable pressure ensures optimal operation of industrial systems.
Material Selection: Pressure level determines the right materials and fittings.
