$($a$)$ If h$51\mathrm{.}00$ m$,$ find the speed of outf low at the end of the siphon. $($b$)$ What If$?$ What is the limitation on the height of the top of the siphon above the end of the siphon? Note: For the f low of the liquid to be continuous, its pressure must not drop below its vapor pressure. Assume the water is at $20\mathrm{.}08$C$,$ at which the vapor pressure is $2\mathrm{.}3$kPa$.$
