Answer :
Final answer:
The maximum allowable natural gas pressure in an industrial mechanical room is determined by local building codes and safety standards and can vary, but typically does not exceed 60 psi. It's essential to consult with local codes like the IFGC or NFPA for precise limits. None of the options matches, so, the correct answer is none of this.
Explanation:
The question regarding the maximum allowable natural gas pressure in an industrial mechanical room is a topic associated with safety regulations within the field of engineering. The specific value would be determined by local building codes and safety standards. However, generally speaking, lower-pressure systems in buildings are often designed for pressures in the range of 0.25 psi to 5 psi, whereas higher-pressure systems could exceed this range but typically do not exceed 60 psi for indoor piping systems.
It's critical to consult the specific codes and standards of your local authority having jurisdiction (AHJ), such as the International Fuel Gas Code (IFGC) or the National Fire Protection Association (NFPA), for the exact allowable pressure limits for an industrial setting.The information provided in the question references various pressure measurements like psi, mm Hg, and atmospheres (atm), which relate to the study of fluid mechanics in physics. These concepts are integral to understanding how to measure and manage the pressure of gases in different settings, including industrial mechanical rooms.
