Which calculation is used to determine the travel for a 60-degree offset?

The calculation used to determine the travel for a 60-degree offset is 1.15 times the offset length. This factor accounts for the angle created by the offset and helps in adjusting the length of pipe needed to reach from one point to another when the angle deviates from a straight line.

For a 60-degree offset, the geometry of the situation creates a need for this adjustment because the resulting travel distance along the pipe must be longer than the direct line distance between two points due to the angle at which the pipe is installed. The 1.15 multiplier is specifically designed to provide a precise measurement for the increase in length required to maintain the correct alignment and slope of the plumbing system while accommodating the offset.

Utilizing this factor ensures that the plumbing installation remains efficient and effective, avoiding issues such as improper drainage or pressure loss, which can occur if the wrong measurements are taken.
