New explicit correlation to compute the friction factor under turbulent flow in pipes

HIGHLIGHTS The correlation facilitates the calculation of head losses in hydraulic systems. The correlation was design for regimes of high and low turbulence. The best performance of the correlation is obtained for a range of roughness that goes from 10-2 to 5 × 10-3.

核心亮点：该关联式可便捷计算水力系统内的水头损失（head losses）。本关联式专为高湍流（turbulence）与低湍流流态设计，在粗糙度（roughness）取值范围为10⁻²至5×10⁻³时可获得最优性能。
