Pressure Measurement

one of the key thermodynamic parameters. It

is an intensive property

defined as a ratio between

a force and a unit area, perpendicular to the direction of that

force, on which the force acts.

is defined as the amount of force being applied to an area. As this force is distributedover a specific area, a change in movement of the defined area

is occurring.

just an occurrence that is causing an object to move, either

accelerating or decelerating.

All fluid molecules will be in constant and random

motion, due to which fluid at rest ina vessel, does exerts force on all the walls of the vessel, with which it is in contact.

Also referred as “hydrostatic pressure” is the

pressure of a fluid at rest.

the pressure of a fluid moving.

Any substance that does not conform to a fixed shape

such as liquid or gas.

Defined as a pressure not associated with the fluid

motion, but its state. It is the pressure which would be

indicated by a gauge moving together with the fluid.

A measurement of kinetic energy of a moving fluid and

depends on its velocity and density.
