Part II $[14$ marks$]$

$[5$ marks$]$ Water is pumped through the $300mm-$diameter commercial steel pipe at a volumetric flow rate of $0\mathrm{.}3\frac{m^3}{s}$ from the lower tank to the upper one.

arts $a,b$ and $c$ are independent.

$[2$ marks$]$ The friction loss $F($in $($:$\frac{m^2}{s^2}\}$ can be expressed as a $f+b,$ where $f$ is the anning friction factor. Include all friction losses. Use the equivalent length approach.
