What is the operating pressure stated for the boiler in the example?

• A. 100 psi
• B. 150 psi
• C. 135 psi
• D. 200 psi

Answer: (C)

Operating pressure is the pressure the boiler is designed to run at under normal operation. In the example, the boiler’s operating pressure is stated as 135 psi. This number matters because it governs how the boiler’s controls regulate feedwater and firing, and it helps determine the settings for safety devices like relief valves and risk management around the maximum allowable pressure. The other numbers are just alternative values you might see in different setups, but the problem clearly specifies 135 psi as the operating pressure, which is why that is the correct choice.
