What is the term for the measurement taken along the center line of a pipe and fitting?

The term for the measurement taken along the center line of a pipe and fitting is developed length. This measurement represents the true lay out length of the pipe, accounting for any bends or fittings that would alter the distance from one end to the other along the centerline. It is a crucial dimension in plumbing and piping design because it helps to determine how much material is needed for installation and ensures that the system functions properly without unexpected restrictions or pressure drops.

Developed length is particularly important in various calculations related to fluid dynamics and installation procedures. This length helps in ensuring that the piping system will run efficiently, avoiding turbulence and improper flow characteristics that might occur if the lengths were approximated incorrectly. Understanding this term and its application is vital for anyone involved in plumbing or related fields.
