Q

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?

🔍 Key Concepts

• Difference between gauge pressure (psig) and absolute pressure (psia) • Typical value of standard atmospheric pressure in psi • How to convert between psig and psia using a simple formula

💭 Think About

• Ask yourself: Does a gauge that reads in psig include atmospheric pressure in its reading, or is it measuring how much the pressure is above/below the atmosphere? • Once you know what the 43.8 psig represents, should you be adding or subtracting atmospheric pressure to find absolute pressure? • Use an approximate value for standard atmospheric pressure in psi, do the math, and then see which option is closest.

✅ Before You Answer

• Remember that psia = ? + ? (think about what two pressures are being combined). • Use standard atmosphere ≈ 14.7 psi unless the question states otherwise. • After calculating, check which option matches your result numerically and with correct units (psia).
