An ASME tanks ______ is used to determine the discharge capacity requirements for its relief valve(s).

• A. Data Plate
• B. Data Place
• C. Data Sheet
• D. Label

Answer: (B)

The most important source for sizing a relief valve on an ASME tank is the data plate that’s attached to the vessel. This plate carries the official design and operating parameters—such as the maximum allowable working pressure (MAWP), the service and contents, and test data—that define how the tank can be safely charged and what amount of overpressure needs to be vented. When you determine the discharge capacity requirements, you use these values to ensure the relief device can remove heat or mass quickly enough to keep the pressure from exceeding the MAWP under the worst‑case scenario. The data sheet can provide detailed design information, and a label might identify the tank, but the data plate is the authoritative source for calculations related to relief sizing. The term “data place” isn’t a standard reference, so focus on the data plate as the primary source for these determinations.
