A $50-mm$ diameter commercial steel pipe $(k_s=0\mathrm{.}046(mm))$ has a length of $100m.$ Find the head

loss for water when the discharge rate is $($a$)0\mathrm{.}1\frac{L}{s}$ and $($b$)1\frac{L}{s}.$ Assume that the water has a

kinematic viscosity $($n$)$ of $1\mathrm{.}518{10}^{-6}\frac{m^2}{s}.$ Ans.: $($a$)h_f=0\mathrm{.}01m,($b$)h_f=0\mathrm{.}77m$
