Question

Types of pressure and its kinds ​

Answer 1

Explanation:

There are two basic pressure types: absolute and gauge, distinguished by what pressure they are compared to, which is called the reference pressure. Gauge pressure's reference is ambient atmospheric pressure. Absolute pressure's reference is an absolute vacuum.

Answer 2

Explanation:

Pressure- : Pressure simply it is defined as the magnitude of the normal force acting per unit area. Pressure comes under scalar quantity

SI UNIT-: Pascal(Pa), 1 Pa = 1N/m².

$\sf \bold{{Dimension:} | {M}^{1}{L}^{ - 1}{T}^{ - 2} | }$

Types of Pressure-

(i) Atmospheres Pressure-

Pressure exerted by the atmosphere is known as atmospheric pressure. Barometer is used to measure the atmospheric pressure.

(ii) Gauge Pressure-

When the pressure is excess to atmospheric pressure then it is measured with the help of measuring instrument known as manometer and that pressure is known as guage pressure.

(iii) Absolute Pressure-

It is collection of both atmospheric pressure and guage pressure.
