Water is siphoned from a large tank and discharges into the atmosphere through a 2-in.-diameter tube as shown in the figure below. The end of the tube is 3 ft below the tank bottom, and viscous effects are negligible. Determine the volume flowrate from the tank. Determine the maximum height, H, over which the water can be siphoned without cavitation occurring. Atmospheric pressure is 14.7 psia, and the water vapor pressure is 0.26 psia

1) Apple juice at 20oC is siphoned from a large tank using a constant-diameter (1.5 cm) hose. The end of the siphon is 1 m below the bottom of the tank. Calculate the volumetric flow rate of juice in the hose and the height of the hill over which the hose may be siphoned without cavitation. Assume properties of the apple juice are the same as water. The atmospheric pressure is 101.3 kPa. Height of the juice in the tank...
