Q

A pressure reading of 00.0 psig is theoretically equal to __________.

🔍 Key Concepts

• Difference between psig (pounds per square inch gauge) and psia (pounds per square inch absolute) • Meaning of a zero gauge pressure reading relative to atmospheric pressure • Standard atmospheric pressure value in different units (psi, inches of mercury, etc.)

💭 Think About

• When a gauge reads 00.0 psig, what pressure is it actually measuring against—vacuum or atmosphere? • How does absolute pressure relate to gauge pressure at standard atmospheric conditions? • If atmospheric pressure is about 14.7 psi, what would the absolute pressure be when gauge pressure is zero?

✅ Before You Answer

• Be clear on the definition: psig = psia − atmospheric pressure • Remember approximate standard atmospheric pressure ≈ 14.7 psia at sea level • Check which choice correctly represents the absolute pressure when the gauge shows zero
