SUMMARY
The volumetric flow rate through a fully developed turbulent channel flow can be derived using the Darcy-Weisbach equation, which relates the friction factor to pressure loss in closed channel flow. The friction factor for turbulent flow can be determined using empirical correlations such as the Colebrook-White equation. Unlike laminar flow, turbulent flow requires consideration of both the Reynolds number and the relative roughness of the channel. Understanding these relationships is crucial for accurately calculating flow rates in engineering applications.
