Answer:
The absolute pressure of the system is 12.7 psia.
Explanation:
Let suppose that system works at an atmospheric pressure of 14.7 psia, the absolute pressure is equal to the atmospheric pressure minus vaccum pressure, that is:
[tex]p_{abs} = p_{atm} - p_{vac}[/tex]
Where:
[tex]p_{abs}[/tex] - Absolute pressure, measured in pounds per square inch.
[tex]p_{atm}[/tex] - Atmospheric pressure, measured in pounds per square inch.
[tex]p_{vac}[/tex] - Vacuum pressure, measured in pounds per square inch.
Given that [tex]p_{atm} = 14.7\,psia[/tex] and [tex]p_{vac} = 2\,psia[/tex], the absolute pressure of the system is:
[tex]p_{abs} = 14.7\,psia-2\,psia[/tex]
[tex]p_{abs} = 12.7\,psia[/tex]
The absolute pressure of the system is 12.7 psia.
