A syphon is used to transfer water from a 8 m deep open tank filled with water using a hose of diameter 5 cm, that has one end placed in the tank at 5 m below the water surface in the tank. The hose exits the top of the tank to a height of 4 m above the water level then drops vertically downward so that its exit to the atmosphere is 1 m below the inlet to the hose in the tank. Determine the exit velocity (m/s) of the water from the syphon.
