The water flows from a tank A whose surface is at level $20$ to another B with a free surface at level $5,$ through a siphon whose highest point is at level $25.$

The total length of the pipe is $100$ m$.$ and the highest point is in the middle of the pipe, whose diameter varies uniformly by $1\mathrm{.}00$ m$.$ in tank A at $0\mathrm{.}5$ m$.$ In b$.$

It is requested, assuming that there are no losses due to friction:

a$)$ The flow that circulates.

b$)$The pressure at the highest point

c$)$ To what height could the highest point be raised, without producing cavitation Y water $20\backslash$deg $=998$ Kg$/$m$^3$

P water vapor at $20\backslash$deg $=0\mathrm{.}23$ T$/$m$2\mathrm{.}1$ agua $20=998K\frac{g}{m^3}$

$P$ vapor $do$ agua $a20=0,23\frac{T}{m}2.$
