A vacuum gauge mounted on a condenser reads 0.66 m hg. What is the absolute pressure in the condenser in KPa when the atmospheric pressure is 101.3 KPa.?
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

![PRESSURE
➤ a scalar quantity
> is the force applied perpendicular to the surface of an object per
unit area over which that force is distributed
> We speak of pressure only when we deal with a gas or a liquid. The
counterpart of pressure in solids is normal stress. Since pressure is defined
as force per unit area, it has the unit of newtons per square meter (N/m²),
which is called a pascal (Pa).
