Verified Answer :

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

A101.325 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

\(P_{ab}=P_{g}+P_{atm}\)

\(P_{g}=P_{ab}-P_{atm}\)

Put the value into the formula

\(P_{g}=550.280-101.325\)

\(P_{g}=448.955\ kPa\)

Hence, The Gage pressure  is 448.955 kPa.
