Final answer:
The burst pressure of a rupture disk on a low-pressure chiller is specified by the manufacturer based on design and safety requirements. This pressure varies, but it is crucial for preventing system failure from overpressurization.
Step-by-step explanation:
The rupture disk on a low-pressure chiller typically has a burst pressure that is designed to prevent catastrophic failure of the system due to overpressurization. This value is determined based on the specific design and safety requirements of the chiller system and can vary depending on the manufacturer specifications and operating conditions. In the given reference where a high-pressure gas cylinder's safety is being evaluated, a rupture pressure of 40 atm is mentioned for gas cylinders containing chlorine. While this figure is for a high-pressure situation and a different application, it can give an indication that rupture disks must have a burst pressure appropriate to the potential pressure they may encounter to ensure safe operation.
