In the pipe system shown below the pipe has a diameter of $42cm,$ and it is $335m$ long from A to $S.$ The equivalent roughness height of the pipe, e$,$ is $0\mathrm{.}15mm.$ The kinematic viscosity is $n=1\mathrm{.}1310-6m\frac{2}{s}.$ The minor head loss coefficients are: KKe $=0\mathrm{.}5$ for entrance losses, and $Kd=1\mathrm{.}0$ for exit losses. The water surface elevations are $h1=745m,$ and $h2=550m.$ The discharge is $Q=485\frac{L}{s}.$

Determine the velocity of the flow between reservoirs in $\frac{m}{s}.$
