For both problems assume water temperature is $20$C$.$

$1)$ Given the following pipe network $($you may assume all pipes are at the same elevation$)$

Pipe Length $($m$)$ Diameter $($m$)$ Friction Factor $\backslash$lambda

AB $3000\mathrm{.}30\mathrm{.}016$

BE $3000\mathrm{.}20\mathrm{.}016$

ED $3000\mathrm{.}20\mathrm{.}016$

AD $3000\mathrm{.}30\mathrm{.}016$

DG $3000\mathrm{.}30\mathrm{.}016$

GH $3000\mathrm{.}20\mathrm{.}016$

EH $3000\mathrm{.}20\mathrm{.}016$

BC $3000\mathrm{.}20\mathrm{.}016$

CF $3000\mathrm{.}20\mathrm{.}016$

EF $3000\mathrm{.}30\mathrm{.}016$

a$)$ Estimate the flow in each pipe $($ignore minor$/$local losses$)..$

b$)$ Are the friction factors reasonable $($assume pipe ks $=0\mathrm{.}00012$ m$)?$
