Problem $3$:

The high$-$pressure ductile$-$iron pipeline shown in Figure becomes divided at point $B$ and rejoins

at point C$.$ If the pressure at point A is $900$ kPa and the pressure at point B is $250$ kPa $,$ calculate

the flow rate at each pipe. Ignore minor losses and use Darcy$-$Weisbach equation to calculate

friction losses with friction factor
