A liquid is flowing through a horizontal straight commercial steel pipe at $4\mathrm{.}57\frac{m}{s}.$ The

inside diameter of the pipe is $2\mathrm{.}067in.(0\mathrm{.}0525m).$ The viscosity of the liquid is $4\mathrm{.}46{10}^{-3}$

$k\frac{g}{m}.s$ and the density is $801k\frac{g}{m^3}.$ Calculate the mechanical energy friction loss $(h_f)$ in $\frac{J}{k}g$

for a $36\mathrm{.}6-m$ section of the pipe.
