For a natural gas system with a 6" W.C. supply pressure and black iron pipe, which table should be referenced for maximum .5" W.C. pressure drop?

6.2.1(A)
6.2.1(B)
6.3.1(D)
6.3.1(F)

The correct answer is: 6.2.1(B)

Referencing the appropriate table for a natural gas system is crucial for ensuring the system functions effectively given specific parameters, including supply pressure and the acceptable pressure drop. In a natural gas system with a 6" W.C. supply pressure and a black iron pipe, the correct table to consult for determining the maximum allowable pressure drop is indeed 6.2.1(B). This table is designed to provide information relevant to the sizing and performance parameters associated with a natural gas system. The specification of a maximum .5" W.C. pressure drop indicates that this table will help identify the capacities and flow characteristics of black iron piping under a specified pressure scenario. The data within the table helps gas fitters understand how to maintain the pressure drop within acceptable limits while ensuring safe and efficient operation. Using the correct table is pivotal, as each one may pertain to different materials, pressure standards, or gas types, and thus using the right reference ensures compliance with design standards and safety regulations in gas fitting installation.
