Water is siphoned from the tank shown in the Figure below. The water barometer indicates a reading of 30.2 ft. Note: the pressure of the vapor in the closed end of the barometer equals the vapor pressure. You may neglect frictional effects while solving this problem. Closed end 3-in. diameter 30.2 ft 6 ft 5-in.-diameter (1.a) Write an expression for the pressure at the top/bend in the siphon, as a function of the mean velocity of the fluid there. (1.b) Determine the maximum value of h allowed without cavitation occurring in the siphon.

Question
**Siphon Problem Description** Water is siphoned from the tank shown in the figure below. The water barometer indicates a reading of 30.2 ft. Note: the pressure of the vapor in the closed end of the barometer equals the vapor pressure. You may neglect frictional effects while solving this problem. **Diagram Explanation:** - The diagram depicts a siphon system involving a large tank filled with water, an inverted U-shaped tube, and a barometer. - Water is siphoned from a tank. - The vertical part of the tube has a closed end, reaching 30.2 ft from the water surface to the top of the siphon. - The siphon consists of two sections: one with a 3-inch diameter pipe rising 6 ft above the tank, and the other with a 5-inch diameter, which descends to an unknown depth labeled "h". - The tank and siphon are connected, allowing water to flow through the system. **Questions to Solve:** (1.a) Write an expression for the pressure at the top/bend in the siphon, as a function of the mean velocity of the fluid there. (1.b) Determine the maximum value of \( h \) allowed without cavitation occurring in the siphon.
