How can you convert a measurement of 10 PSIG to PSIA?

How can you convert a measurement of 10 PSIG to PSIA?

• A. 10 PSIG + 14.7 = 24.7 PSIA
• B. 10 PSIG - 14.7 = -4.7 PSIA
• C. 10 PSIG x 14.7 = 147 PSIA
• D. 10 PSIG ÷ 14.7 = 0.68 PSIA

Answer: (A)

To convert a measurement from PSIG (pounds per square inch gauge) to PSIA (pounds per square inch absolute), you need to add the atmospheric pressure to the gauge pressure. Atmospheric pressure at sea level is approximately 14.7 psi. In this scenario, when you have a gauge pressure of 10 PSIG, it means the pressure is 10 psi above atmospheric pressure. To find the absolute pressure (PSIA), you simply take the gauge pressure and add the atmospheric pressure: 10 PSIG + 14.7 psi = 24.7 PSIA. This calculation is essential in many engineering and operational contexts, such as when dealing with fluid dynamics, HVAC systems, or any scenario where absolute pressure is necessary for accurate measurements and calculations. By understanding this conversion process, you can ensure that you're using the correct values when assessing systems and making decisions based on pressure measurements.
