The statement '50 psi above system demand' corresponds to approximately how many bar?

The statement '50 psi above system demand' corresponds to approximately how many bar?

• A. 2.0 bar
• B. 2.5 bar
• C. 3.0 bar
• D. 3.4 bar

Answer: (D)

The pressure unit conversion is the key idea here. One bar is about 14.7 psi, so 50 psi translates to 50 divided by 14.7 in bar. Doing the math gives roughly 3.40 bar, which rounds to 3.4 bar. So “50 psi above system demand” corresponds to about 3.4 bar. Even if you use a slightly different conversion (14.5 or 14.5038 psi per bar), you still land around 3.4 bar.
