Learn how to calculate the Darcy friction factor for turbulent pipe flow using the Swamee-Jain equation, which depends on Reynolds number, absolute roughness, and pipe diameter. Compare the Swamee-Jain equation with other methods such as Colebrook-White equation and Moody diagram.
Swamee–Jain equation. The Swamee–Jain equation is used to solve directly for the Darcy–Weisbach friction factor f for a full-flowing circular pipe. It is an approximation of the implicit Colebrook–White equation.

No presente estudo, variaram-se esses parâmetros, de forma a simular todas as situações prováveis de ocorrer em um sistema de recalque para irrigação.
