What is the maximum capacity of natural gas for a 1" nominal size schedule 40 metallic pipe with a run length of 200 feet?

The maximum capacity of natural gas that can be transported through a 1" nominal size schedule 40 metallic pipe is determined by several factors, including the pipe's internal diameter, the pressure drop over the length of the run, and the properties of the gas itself. For a 1" schedule 40 pipe, the internal diameter is typically around 1.049 inches.

When calculating the capacity, you consider the established gas flow formulas that take into account the pressure, the length of the run, and the type of gas being delivered. For a 200-foot long stretch of pipe, it is critical to reference data tables or industry standards that provide flow rates for various pipe sizes under different conditions of pressure and temperature.

In this specific case, the calculation or reference to a capacity chart indicates that, under standard conditions for natural gas with a 200 feet run, the maximum flow rate that can be sustained without excessive pressure loss is approximately 134 cubic feet per hour. This figure aligns with standard engineering practices and flow calculations for gas distribution systems, making it the most accurate answer in this scenario.
