In a siphon, the summit is 3 m above the water level in the reservoir from which the flow is being discharged. If the head loss from the inlet of the siphon to the summit is 1.5 m and the velocity head at the summit is 0.5 m, the absolute pressure at the summit is
1
5.3 m of water
2
9.3 m of water
3
6.3 m of water
4
