What is the equivalent of a 2-inch NPS Schedule 40, 90 degree threaded elbow?

To determine the equivalent length of a 2-inch NPS Schedule 40, 90-degree threaded elbow in terms of straight pipe length, it's essential to understand how fittings can introduce resistance in piping systems, and this is captured by their equivalent lengths.

For a 90-degree threaded elbow, specific values have been established based on factors like flow characteristics and friction. The equivalent length is a way to represent the resistance to flow that these fittings cause, allowing engineers to account for their impact when calculating pressure drops in a piping system.

In this case, the correct equivalent length for a 2-inch NPS Schedule 40 elbow is known to be approximately 5.17 feet. This value is derived from standard engineering tables that provide equivalent lengths for various sizes and types of fittings. These tables are populated with extensively researched data that reflect the hydraulic loss characteristics when fluid flows through these fittings.

Understanding these equivalencies is crucial for maintaining efficient flow and proper hydraulic design in gas systems. Being able to convert the resistance of fittings into equivalent lengths helps technicians accurately model the performance of piping systems, ensuring safety and efficiency in gas installations.

Thus, the answer 5.17 feet accurately represents the equivalent length of a 2-inch NPS Schedule 40, 90
