What does developed length refer to in plumbing?

Developed length in plumbing specifically refers to the total length of the pipe measured along the centerline. This measurement is crucial for various calculations, including those involving flow rates, pressure losses, and the overall efficiency of a plumbing system. By considering the developed length, plumbers can accurately predict how water will travel through the system, including any potential bends or fittings that might impact flow.

Measuring along the centerline allows for a uniform way to account for the full distance the water will travel, as opposed to simply measuring straight spans or considering only the vertical components of plumbing installations. This concept helps in adhering to building codes and ensuring that systems are designed for optimal performance and durability.
