Pressure (symbol: p) is the force applied per unit area, in the direction perpendicular to that surface.
P=F/A, where, F is the normal force, A is the area.
Pressure is a scalar, which in IS is measured in pascals.
1 Pa = 1 N/m2
The pressure is transmitted to surrounding areas or sections of the field of fluid, in the normal direction at any point in these areas or sections.
It is a fundamental parameter in thermodynamics and is a joint variable to volume.
