A suction device is being designed based on the Venturi principle to life objects in submerged water. The operating water temperature is 50C. The suction cup is located 1.3 m below the water surface, and the Venturi throat is located 1 m above the water. The atmospheric pressure is 100 kPa. The ratio of the throat area to the exit area is V=4Vexit and the exit area is 0.001m^2. The area of the suction cup is 0.25 m^2. What is the velocity of the water at the exit for maximum lift condition?
