PROBLEM. $3L_1=100m*P_1$

Consider the pipe$-$network given below.

For whole pipes William$-$Hazen friction factor of $C=90.$ All pipes have $D=30C$

Note that $h_f=\frac{l}{(0\mathrm{.}279C{)}^{1\mathrm{.}85}}\frac{1}{D^{4\mathrm{.}07}}{Q}^{1\mathrm{.}85}.,S$

a$)$ Find the discharges in whole pipes of the network.

b$)$ If the energy $($piezometric level$)$ at the node point A is $100$ m what is the pressure at the point G whose distance to A and the geometrical elevation are $150$ m and $85$ m $,$ respectively. For water take $=9810\frac{N}{m^3}.$

ANSWERS $($TRUE$)$;

$($a$)Q_{\text{A}\text{G}\text{B}}=23\mathrm{.}85l\frac{t}{s}$;$Q_{BE}=16\mathrm{.}61l\frac{t}{s}$;$Q_{DE}=18\mathrm{.}34c\frac{t}{s}$;$Q_{CD}=26\mathrm{.}15c\frac{t}{s}$

$($b$)P_E=14\mathrm{.}6392\frac{N}{m^2}=146\mathrm{.}392k\frac{N}{m^2}$
