Question

what is the gauge pressure​

Answer 1

Answer:

$\huge\fbox \red{Answer}$

Pressure measurement is the analysis of an applied force by a fluid on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum.

Answer 2

Answer:

Gauge pressure is the pressure relative to atmospheric pressure. Gauge pressure is positive for pressures above atmospheric pressure, and negative for pressures below it. In fact, atmospheric pressure does add to the pressure in any fluid not enclosed in a rigid container.
