Using the given source and demands, shown in Fig. Q$5,$ analyse the pipe network.

Pipe resistance values $($R$),$ as shown in Fig. Q$5,$ were calculated assuming that $\backslash$lambda

values are the same for all pipes.

$($a$)$ Using Hardy$-$Cross head balance method, calculate the flow in each pipe at

the end of two trials $($two flow corrections$)$ for an inflow of $5$ L$/$s at the junction

A and outflows of $2$ L$/$s and $3$ L$/$s at junctions D and C respectively.

$($b$)$ Calculate the pressure at the demand nodes if the pressure at the source is

$100$ m$.$

$($c$)$ What will be the effect of closure pipe AB $($due to repair$)$ on the pressure

distribution of the downstream nodes?
