Q$1.$ Given that the valves are $(1)$ closed $(2)$ open: find the absolute and gage pressure of water; and the velocity at the elevations shown, and at the middle of the pipes $($pipe length $=200m,$ diametr $=0\mathrm{.}4m,$ friction factor is $f=0\mathrm{.}02).($Hint: elevation of the middle point of the valve is the average of the sides elevation$).$

Q$2.$ Given that the valves are open and the velosity downstream at $($DS$1)$ is $1\mathrm{.}6\frac{m}{s},$ and at $($DS$2)$ it is $0\mathrm{.}9\frac{m}{s}$; find the pressure of water, and the velocites at the elevations shown and the at the middle point of pipe $1.$ flow is running in smooth$-$plastic pipe $20m-$long and $40cm$ diameter.
