Answer :
Final answer:
A safety relief valve typically opens at 150 PSI to protect air systems from excessive air pressure, ensuring operational safety.
Explanation:
A safety relief valve is used in air systems to prevent excessive air pressure that could lead to system failure or hazards.
This valve is crucial for maintaining the system within safe operational limits. Among the options provided, the correct setting for most safety relief valves in these systems is 150 PSI (pounds per square inch).
This setting helps to ensure that the air pressure in the system does not exceed a safe threshold. Safety relief valves are an essential component in many engineering applications, providing a fail-safe to prevent accidents associated with over-pressurization.
Final Answer:
A safety relief valve, used to protect the air system from excessive pressure, is typically set to open at 150 PSI.
Option c) 150 PSI is the correct answer.
Explanation:
A safety relief valve is a crucial component in preventing overpressurization of air systems. It acts as a safeguard by releasing excess pressure to maintain system integrity. The valve is usually set to open at a specific pressure threshold.
In this case, the correct setting is 150 PSI (option c). This means that if the air pressure surpasses this level, the relief valve will activate, allowing the excess air to escape, preventing potential damage to the system and ensuring the safety of equipment and personnel.
Option c) 150 PSI is the correct answer.
