Solution

Pressure:

  1. The force applied per unit area would be described as pressure.
  2. Pressure is denoted by P.
  3. The S.I unit of pressure is pascal.

Mathematically, pressure can be represented as:

P=FA

Here,

F = Force acting

A = Area

Types of pressure:

There are four different kinds of pressure, such as:

  1. Absolute pressure: The pressure of having no matter or a complete vacuum inside a place is called absolute pressure.
  2. Differential pressure: A measurement of the elevation of a fluid in a device is called differential pressure.
  3. Atmospheric pressure: The weight of the air above a surface exerts a force per unit area against a surface is called atmospheric pressure.
  4. Gauge pressure: The pressure as calculated in relation to the atmospheric pressure is called gauge pressure.
