Type I A $10-$cm$-$diameter galvanized pipe $($e $=0\mathrm{.}05$ mm$)5$ Km long carries $0\mathrm{.}1$ cms at $20$C$.$ Find hL using $($a$)$ the Moody diagram and $($b$)$ the Colebrook eqn.

Type II For the pipe analyzed in the preceding example, what is the largest flow rate allowable if the total frictional headloss must remain $<2\mathrm{.}5$ m$?$

Type III What diameter galvanized pipe would be required in the preceding examples if a flow rate of $0\mathrm{.}3$ cms was needed, while keeping the total frictional headloss at $<2\mathrm{.}5$ m$?$
