If the absolute pressure of a gas is 550.280 kpa, its gauge pressure is a. 448.955 kpa. b. 101.325 kpa. c. 651.605 kpa. d. 277.280 kpa.

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

Now rearrange the above equation to find the gauge pressure:

Insert the values:

Absolute pressure = = 550.280 kPa

Atmospheric pressure = = 101.325 kPa

Gauge pressure = = ?

Hence the correct answer is: Option (A) 448.955 kPa
