🔍 Key Concepts

• Conversion between bar and pounds per square inch absolute (psia) • Remember that 1 bar is approximately equal to 14.5 psia • Distinguishing between gauge pressure (psig) and absolute pressure (psia), even though only absolute is used here

💭 Think About

• First, recall or estimate how many psia are in 1 bar, then multiply by 7 to get close to the answer • Compare your calculated value to the choices and see which one is closest to your estimate • Think about whether the result should be closer to a low pressure (around 20 psia) or a high pressure (around 100 psia) when dealing with multiple bars

✅ Before You Answer

• Verify your conversion factor for 1 bar to psia before doing the math • Carefully multiply the conversion factor by 7 and round reasonably to match the choices • Check that your final value is in absolute pressure (psia), not gauge pressure (psig), even though numerically the conversion step is the same here
