Question

Is gauge pressure larger, smaller, or the same as absolute pressure? is gauge pressure larger, smaller, or the same as absolute pressure? smaller the same greater?

Answer 1

gauge pressure is smaller than absolute pressure.

Step-by-step explanation:

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

`P_(abs) = P_(gauge) + P_(atm)`

where;

`P_(abs)` is the absolute pressure, measured in pounds-per-square-inch (PSI)

`P_(gauge)` is the gauge pressure, measured in PSI

`P_(atm)` is the atmospheric pressure, = 14.7 PSI

`P_(abs) = P_(gauge) + 14.7`

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