Fully rough

WebShow that the flow is fully rough, and thus the friction factor is independent of Reynolds number. The density and dynamic viscosity of water at 15°C are ρ = 999.1 kg/m3 and μ = 1.138 × 10–3 kg/m·s. The roughness of cast iron pipe is ε = 0.00026 m. (Round the final answer to three decimal places.) The flow rate through pipe B is _____ m 3 /s.
