What is the relationship between the size of the blowoff tank outlet and the blowdown piping diameter?

Equal to the diameter of the blowdown piping
2 times the diameter of the blowdown piping
3 times the diameter of the blowdown piping
4 times the diameter of the blowdown piping

The correct answer is: 2 times the diameter of the blowdown piping

The correct answer reflects a standard engineering principle regarding the design of blowoff tanks and blowdown systems. The outlet of the blowoff tank should be designed to be at least two times the diameter of the blowdown piping. This sizing ensures that the blowoff tank can effectively handle the volume of water discharged during the blowdown process without creating excessive pressure or turbulence that could lead to operational issues. By having the blowoff tank outlet larger than the blowdown piping, it facilitates smoother flow, reduces the risk of blockages, and allows for efficient drainage from the system. This relationship is essential for maintaining safety and effectiveness in boiler operations, as proper sizing helps prevent back pressure that could impede the flow of water being removed from the system. In contrast, options suggesting a smaller or larger diameter than twice the blowdown piping do not align with these best practices, potentially leading to inefficient operations or increased risk of maintenance issues. Therefore, the requirement for the blowoff tank outlet to be two times the diameter of the blowdown piping is a recognized standard in boiler design and maintenance.
