$6 \mathrm {~m}$
$\text {The jump would be $H _ { P }$. It is, using Eq. $4.5 .26$ with $\eta _ { P } = 1$ (it is stated in Problem 1}$ $\text {that $2 \mathrm { hp }$ is input into the water),}$
$$H _ { P } = \frac { \dot { W } _ { P } } { \gamma A V } = \frac { 2 \times 746 } { 9810 \times \pi \times 0.04 ^ { 2 } \times 5 } \cong \underline { 6 \mathrm {~m} }$$
