WebDarcy-Weisbach Friction Loss Equation: D is called the "duct diameter" to keep the terminology general to include circular pipes and non-circular pipes, also known as ducts. For rectangular pipes (ducts), D=4A/P is known as the hydraulic diameter. WebNevertheless, a safe way to determine the friction factor (f) was not found early. The determination of the friction factor is a difficult problem to solve; for the steady state as for the transient state. Only in 1939, almost 100 years later, a law was definitely established to determine the friction factor for the permanent
