Question

If a gas has an absolute pressure of 319 kPa, its gage pressure is?

A. 439 kPa.
B. 199 kPa.
C. 419 kPa.
D. 219 kPa.

Answer 1

According to question
We are given that

Absolute Pressure
P(A) = 319 KPa
 Let the atmospheric pressure be   P(atm) = 1 = 101 KPa
Thus According to the formula

P(A) = P(atm) + P(G)
So
P(G) = 319 - 101
P(G) = 218 KPa

Thus the gauge pressure is 218 KPa

Answer 2

Answer:According to question

We are given that

Absolute Pressure

P(A) = 319 KPa

 Let the atmospheric pressure be   P(atm) = 1 = 101 KPa

Thus According to the formula

P(A) = P(atm) + P(G)

So

P(G) = 319 - 101

P(G) = 218 KPa

Thus the gauge pressure is 218 KPa
