Question 29General Subjects - QMED
70% to passIf a standard bourdon tube type pressure gauge that is designed to measure and display gauge pressure reads 43.8 psig, what would be the equivalent absolute pressure?
A29.1 psia
B43.8 psia
C58.5 psia
D61.2 psia
AI Explanation
The correct answer is C) 58.5 psia. To convert a gauge pressure (psig) to an absolute pressure (psia), you need to add the atmospheric pressure, which is typically around 14.7 psi at sea level. Since the gauge pressure reading is 43.8 psig, the equivalent absolute pressure would be 43.8 psig + 14.7 psia = 58.5 psia. The other options are incorrect because: A) 29.1 psia is too low, as it does not account for the atmospheric pressure. B) 43.8 psia is the gauge pressure, not the absolute pressure. D) 61.2 psia is too high, as it exceeds the sum of the gauge pressure and the atmospheric pressure.
