What size corrugated stainless steel tubing should be installed to achieve a flow of 217,000 cubic feet per hour of natural gas at a distance of 98 feet with specific conditions?

To determine the correct size of corrugated stainless steel tubing needed to achieve a flow of 217,000 cubic feet per hour of natural gas over a distance of 98 feet, it is essential to consider the characteristics of gas flow and the pressure drop associated with various tubing sizes.

The sizing of corrugated stainless steel tubing is based on the desired flow rate and the length of the run. The larger the tubing diameter, the lower the pressure drop for a given flow rate. This is crucial in gas systems to ensure that the gas pressure remains adequate to deliver the required volume of natural gas.

Tubing size 30 (EHD) is appropriate for this scenario because it allows for the efficient delivery of 217,000 cubic feet per hour, maintaining an acceptable pressure drop over the specified distance of 98 feet. It strikes a balance between sufficient gas flow capacity and managing the pressure drop that occurs in the system.

In contrast, smaller tubing sizes may not provide adequate flow capacity or could lead to excessive pressure losses, which would compromise the efficiency and effectiveness of the gas delivery. On the other hand, larger sizes may be unnecessary and can increase installation complexity and cost without offering significant performance improvement for this flow rate and distance.

Therefore, tubing size
