------------------------------------------------ If the absolute pressure of a gas is 550.280 kPa, its gauge pressure is:

A. 101.325 kPa
B. 448.955 kPa
C. 651.605 kPa
D. 277.280 kPa

Answer :

If the absolute pressure of a gas is 550.280 kPa, its gage pressure is


a. 101.325 kPa.
b. 448.955 kPa.
c. 651.605 kPa.
d. 277.280 kPa.

The answer is B.

Answer:

The Gage pressure is 448.955 kPa.

(b) is correct option.

Explanation:

Given that,

Absolute pressure = 550.280 Pa

Gage pressure :

The Gage pressure is equal to the subtract the absolute pressure from atmospheric pressure.

We need to calculate the Gage pressure

Using formula of Gage pressure

[tex]P_{ab}=P_{g}+P_{atm}[/tex]

[tex]P_{g}=P_{ab}-P_{atm}[/tex]

Put the value into the formula

[tex]P_{g}=550.280-101.325[/tex]

[tex]P_{g}=448.955\ kPa[/tex]

Hence, The Gage pressure is 448.955 kPa.
