# What is the gauge pressure if the absolute pressure is 321 atm?

## Question:

What is the gauge pressure if the absolute pressure is {eq}321 \ atm {/eq}?

## Gauge Pressure:

Gauge pressure is the pressure above the atmospheric pressure. This pressure is zero-referenced against the ambient air pressure and is determine by getting the difference between absolute pressure and the atmospheric pressure.

Given:

{eq}P_{abs} = 321 \ atm {/eq} Absolute pressure

{eq}P_{atm} = 1 \ atm {/eq} Atmospheric pressure

The gauge pressure can be determined by...
