Question

A rough pipe of 0.5 m0.5\text{ m} diameter, 300 m300\text{ m} length and roughness height of 0.25 mm0.25\text{ mm}, carries water (kinematic viscosity =0.9×10−6 m2/s= 0.9 \times 10^{-6}\text{ m}^2\text{/s}) with velocity of 3 m/s3\text{ m/s}. Friction factor (ff) for laminar flow is given by f=64/Ref = 64/R_e, and for turbulent flow it is given by 1f=2log⁡10(rk)+1.74\frac{1}{\sqrt{f}} = 2 \log_{10} \left( \frac{r}{k} \right) + 1.74 where, Re=Reynolds numberR_e = \text{Reynolds number}, r=radius of piper = \text{radius of pipe}, k=roughness heightk = \text{roughness height} and g=9.81 m/s2g = 9.81\text{ m/s}^2. The head loss (in m, up to three decimal places) in the pipe due to friction is ______
