SUMMARY
The discussion centers on calculating the Darcy-Weisbach friction factor using limited information, specifically when the Reynolds number is unknown. The user, Ben, has provided parameters including a roughness height (K = 0.02 mm), pipe diameter (D = 150 mm), and flow rate (Q = 100 l/s). To find the Reynolds number, the formula RE = (density) x (velocity) x (diameter of pipe) / (dynamic viscosity) is suggested, but the fluid type remains unspecified. Participants recommend assuming fully developed turbulent flow to proceed with the calculation.
