For systems with an inlet pressure of less than 2 psi, what supply rate is standard for natural gas?

In systems with an inlet pressure of less than 2 psi, the standard supply rate for natural gas is typically set at 1000 CFH (Cubic Feet per Hour). This standard is often based on the requirements for low-pressure gas appliances and ensures efficient operation while maintaining safety standards.

Natural gas appliances designed for low-pressure systems generally operate effectively within this supply rate, making it a widely accepted figure in the industry. This benchmark has been developed to optimize performance and efficiency, ensuring that appliances receive an adequate and consistent flow of gas for proper combustion and operation.

Other values you might encounter for higher inlet pressures or different systems reflect various designs and codes; however, they would not apply to the low-pressure context specified in the question.
