If the capacity of an 80-foot, 23 EHD CSST is required given certain pressures and specific gravity, what is the capacity in cfh?

To determine the capacity in cubic feet per hour (cfh) for an 80-foot, 23 EHD CSST (Corrugated Stainless Steel Tubing) at certain pressures and specific gravity, it’s important to apply the formula used in gas flow calculations that takes into account the diameter of the pipe, the length of the run, and the gas pressure.

For specifically sized tubing like 23 EHD, you can use tables or calculations available in HVAC and gas piping resources that outline the carrying capacity of different pipe sizes under various conditions. In this case, if the parameters such as pressure drop and specific gravity have been accurately determined and plugged into the flow calculation formula or reference tables, the resulting capacity would indeed be 141 cfh.

The choice of 141 cfh aligns with the recognized calculations pertinent to the gas flow characteristics through this specific type and configuration of piping. Accurate tables or formulas factor in parameters such as pipe length, internal diameter, pressure loss, and the properties of the gas being transported. This academic and technical backing ensures that the selected capacity is consistent with engineering principles applied in designing gas piping systems.

It is critical for those involved in HVAC design and gas piping installations to understand how to derive these values, as they directly
