$24(25$ pts$)$ Determine the maximum allowable height to avoid cavitation at the contraction $($section $1).$ 'ipe diameter is $d=0\mathrm{.}1m.$ Take the absolute vapor pressure $($cavitation pressure$)$ for water $Pv=2\mathrm{.}45$kPa and he atmospheric pressure $P_{\text{a}\text{t}\text{m}}=100$kPa. Fluid is ideal. Draw the hydraulic grade line of the system. $\frac{{}_1^2}{2g}+\frac{p_1}{}+z_1=\frac{V_2^2}{2g}+\frac{p_2}{}+z_2$
