Water (with density of \( \rho=1000 \mathrm{~m}^{3} / \mathrm{s} \) and \( \mu=0.001 \mathrm{Ns} / \mathrm{m}^{2} \) ) is flowing through a horizontal pipe, whose diameter is \( D=1 \mathrm{~m} \) and length \( L=100 \mathrm{~m} \). The roughness of pipe is \( \varepsilon=2 \mathrm{~mm} \). The flow is fully turbulent with a Reynolds number of \( R e_{D}= \) \( 10^{6} \). Determine the head loss. a) \( 0.115 \mathrm{~m} \) b) \( 0.230 \mathrm{~m} \) c) \( 0.0714 \mathrm{~m} \) d) \( 0.427 \mathrm{~m} \) e) \( 0.902 \mathrm{~m} \)
