Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API 650 open top welded storage tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 open top welded storage tanks design, supply, fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached Datasheets and/or Drawings.
