Q$3$ Water flows through the $20$ mm diameter cast iron pipe such that it discharges at C from the fully open gate valve at B as seen in Figure Q$3.$ The flow rate is $3\frac{L}{c}.$

Figure Q$3$: Pipe System from A to C

Find the following for this pipe system;

$($i$)$ The velocity of the water, V

$($ii$)$ The Reynolds Number, Re

$($iii$)$ The friction factor, $($You must include the Moody Diagram$)$
