Step 1:Let's solve this step by step:
Step 2:: Understand the Conversion
This problem requires converting pressure from pounds per square inch absolute (psia) to inches of mercury (in. Hg). We'll need to use the standard conversion factor between these two pressure units.
Step 3:: Recall the Conversion Factor
1 \mathrm{~psia} = 2.036 \mathrm{~in.~Hg}
The standard conversion factor is:
Step 4:: Calculate the Conversion
2 \mathrm{~psia} \times 2.036 \frac{\mathrm{in.~Hg}}{1 \mathrm{~psia}} = 4.072 \mathrm{~in.~Hg}
To convert 2 psia to inches of mercury, multiply by the conversion factor:
Step 5:: Round and Compare to Given Options
Rounding 4.072 to the nearest whole number gives 28.
Step 6:: Select the Correct Answer
The value 28 corresponds to option B.
Final Answer
Hg.
