Problem $8\mathrm{.}4\mathrm{.}11$

A $40-$m$-$long, $12-$mm$-$diameter pipe with a friction factor of $0\mathrm{.}020$ is used to siphon $30C$ water from a tank as shown in Fig. P$8\mathrm{.}4\mathrm{.}11.$ Determine the maximum value of $h$ allowed if there is to be no cavitation within the hose. Neglect minor losses.
