The minimum working pressure of 175 psi is approximately equal to how many bar?

The minimum working pressure of 175 psi is approximately equal to how many bar?

• A. 12.1 bar
• B. 10 bar
• C. 15 bar
• D. 8 bar

Answer: (A)

Converting pressure between psi and bar. 1 bar equals about 14.5038 psi. To get the bar value from psi, divide by 14.5038. So 175 psi ≈ 175 ÷ 14.5038 ≈ 12.06 bar, which rounds to about 12.1 bar. The other options correspond to pressures far from 175 psi (for example, 10 bar is about 145 psi, 8 bar about 116 psi, and 15 bar about 217.5 psi), so 12.1 bar is the correct approximation.
