Given a situation where only galvanized pipes $($f $=0\mathrm{.}021$ and in sizes of x $50$ mm$)$ are available and the water need to be transported a distance of $1\mathrm{.}2$ km long, what pipe size do you think would be required if a flow rate of $24192$ m$3/$d was needed, while keeping the total friction headloss at less than $2\mathrm{.}0$ m$?$
