To convert a pressure of 10 psi to inches of mercury, we need to use the conversion factor between psi and inches of mercury.
1. Know that 1 psi is approximately equivalent to 2.036 inches of mercury.
2. To find out how many inches of mercury 10 psi is equal to, you multiply the pressure in psi by the conversion factor.
Calculation:
[tex]\[ 10 \, \text{psi} \times 2.036 \, (\text{inches of Hg per psi}) = 20.36 \, \text{inches of mercury} \][/tex]
Upon comparing the result to the provided options:
- Option A: 15 inches of mercury
- Option B: 20 inches of mercury
- Option C: 50 inches of mercury
- Option D: 100 inches of mercury
The closest value to 20.36 inches of mercury is option B: 20 inches of mercury.
Therefore, the pressure of 10 psi converts to approximately 20 inches of mercury, making option B the correct choice.
