Question

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.

Answer 1

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 2

The Gage pressure is 448.955 kPa.

(b) is correct option.

Step-by-step 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.
