Answer :
Final Answer:
The safety valve opens at a maximum pressure of 150 psi, determined by system design and safety standards. This ensures timely pressure relief to prevent equipment failure and maintain a safe operating environment.Thus the option C is correct.
Explanation:
The correct pressure level at which the safety valve will open to allow excess air pressure to escape is 150 psi. This value is determined based on the system's design specifications and safety standards. It ensures that the pressure relief mechanism activates before reaching a critical point that could lead to equipment failure or hazardous conditions. The safety valve's role is crucial in maintaining a safe operating environment by preventing the system pressure from exceeding the designated limit.
In industrial settings, the selection of the safety valve's set pressure involves considering various factors such as the system's maximum allowable working pressure (MAWP), potential overpressure scenarios, and safety regulations. Engineers calculate and set the safety valve pressure to ensure that it provides adequate protection without opening prematurely or too late. The specified value of 150 psi indicates the threshold at which the safety valve intervenes, releasing excess pressure and safeguarding the system from potential damage.
It's essential to adhere to these pressure specifications to guarantee the safety and reliability of the equipment and the overall system. Properly calibrated safety valves play a critical role in preventing catastrophic failures, ensuring the longevity of machinery, and safeguarding personnel in industrial environments.Thus the option C is correct.
