Find the flow rates $($in $\frac{L}{})$ ia each pipeline $($P$1,$ P$2,$ P$3)$ and the presonge $($is ra$)$ at Node NI fox the followieg system. Pipe leng he mad diameters are marked on the figure.

II$.$ Dras the hytruilic grade lint for the system.

Given:

Rate of withdrawl at NI $,-21\frac{L}{s}$

Energy input by pump $($in $m)=68-640Q^3$ where $Q$ is in $m^{\frac{3}{s}}$
