Answer:

gauge pressure is smaller than absolute pressure.

Explanation:

The relationship between absolute pressure and gauge pressure is given as;

[tex]P_{abs} = P_{gauge} + P_{atm}[/tex]

where;

[tex]P_{abs}[/tex] is the absolute pressure, measured in pounds-per-square-inch (PSI)

[tex]P_{gauge}[/tex] is the gauge pressure, measured in PSI

[tex]P_{atm}[/tex] is the atmospheric pressure, = 14.7 PSI

[tex]P_{abs} = P_{gauge} + 14.7[/tex]

Thus, from the relationship above, it can be easily deduced that gauge pressure is smaller than absolute pressure.
