Where p = fluid's density (kg/m³), V = velocity (m/s) and µ = dynamic viscosity (N-s/m²). In addition, the Reynolds number also serves as the criterion for whether flow is turbulent (Re > 4000). Using any numerical root-finding method, determine the friction factor for air flow through a smooth, thin tube. For this case, the parameters are given. Note that friction factors range from about 0.008 to 0.08. Report all your answers accurate to 3 decimal places. Use a tolerance of 10-6. p = 1.23 kg/m³ ,µ = 1.79x10-5 Ns/m², D = 0.005 m, V = 40 m/s, and e = 0.0015 mm
