Question

Marshall determines that a gas has a gage pressure of 276 kPa. What's the absolute pressure of this gas?

Answer 1

377 kPa

Step-by-step explanation:

The absolute pressure of a gas is given by the sum of its gauge pressure and the atmospheric pressure:

`p=p_0 + p_g`

where

`p_0 = 101 kPa` is the atmospheric pressure

`p_g` is the gauge pressure of the gas

In this problem, the gauge pressure of the gas is
`p_g = 276 kPa`. Therefore, the absolute pressure is

`p=101 kPa+276 kPa=377 kPa`
