Question

What are the different types of pressure?

Answer 1

Pressure:

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

Mathematically, pressure can be represented as:

$\mathrm{P}=\frac{\mathrm{F}}{\mathrm{A}}$

Here,

$\mathrm{F}$ = Force acting

$\mathrm{A}$ = 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.
