Different Types of Pressure

The pressure is defined as the force acting per unit area. Following are the different types of pressure based on the reference pressure:

  • Absolute pressure: Pressure which is related to reference pressure is known as absolute pressure.
  • Differential pressure: The difference between the two pressures is equal to the differential pressure.
  • Atmospheric pressure: Pressure related to the atmosphere that surrounds the earth is atmospheric pressure. This pressure is weather-dependent.
  • Gauge pressure: This is the difference between absolute pressure and atmospheric pressure.
