If 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?

Correct Answer: Option C — 58.5 psia

Absolute pressure is the sum of gauge pressure and atmospheric pressure. Using the standard atmospheric pressure of 14.7 psia, the calculation is 43.8 psig + 14.7 psi = 58.5 psia. This conversion is essential for thermodynamic calculations involving vacuum or pressurized systems in marine engineering.
