Question 29General Subjects - QMED

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.
