Answer :
The correct answer is: Option (A) 448.955 kPa
Explanation:
The formula for the absolute pressure is given as:
Absolute-pressure = Gauge-pressure + Atmospheric-pressure
[tex]P_{abs} = P_g + P_{atm}[/tex]
Now rearrange the above equation to find the gauge pressure:
[tex]P_{g} = P_{abs} - P_{atm}[/tex]
Insert the values:
Absolute pressure = [tex]P_{abs}[/tex] = 550.280 kPa
Atmospheric pressure = [tex]P_{atm}[/tex] = 101.325 kPa
Gauge pressure = [tex]P_{g}[/tex] = ?
[tex]P_{g} = 550.280 - 101.325[/tex]
[tex]P_{g} = 448.955 kPa[/tex]
Hence the correct answer is: Option (A) 448.955 kPa

Answer:
The correct answer is option A which is 448.955 kPa.
Explanation:
Given data:
absolute pressure of a gas = Pabs = 550.280 kPa
Atmospheric pressure = Patm = 101.325 kPa
Gauge pressure = Pg = ?
Solution:
As we know gauge pressure is difference of Absolute pressure and atmospheric pressure.
Pg = Pabs - Patm
Pg = 550.280 kPa - 101.325 kPa
Pg = 448.955 kPa
Hence the gauge pressure is 448.955 kPa
