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

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



Answer :

Absolute pressure is the sum of  gauge pressure and the atmospheric pressure. Gauge pressure is the pressure measured above atmospheric. 

Calculations are as follows:
319 kPa = Gauge pressure + 101.325 kPa

Gauge pressure =  217.68 kPa
