In the pipe system shown below the pipe has a diameter of $21cm,$ and it is $530m$ long from $A$ to $S.$ The equivalent roughness height of the pipe, $e,$ is $0\mathrm{.}22mm.$ The kinematic viscosity is $n=1\mathrm{.}1310\mathrm{.}6m\frac{2}{s}.$ The minor head loss coefficients are: Ke $=0\mathrm{.}5$ for entrance losses, and $Kd=1\mathrm{.}0$ for exit losses. The water surface elevations are $h1=730m,$ and $h2=650m.$ The discharge is $Q=525\frac{L}{s}.$

Determine the pressure head at $S$ in $m.$
