A siphon draws water from a reservoir and discharges it out at atmospheric pressure. Assuming ideal fluid and the reservoir is large, the velocity at point P in the siphon tube is:
1
\(\sqrt {2g{h_1}}\)
2
\(\sqrt {2g{h_2}}\)
3
\(\sqrt {2g\left( {{h_2} - {h_1}} \right)}\)
4
\(\sqrt {2g\left( {{h_2} + {h_1}} \right)}\)
