A suction device is being designed based on the venturi principle to lift objects submerged in water. The operating water temperature is 15°C. The suction cup is located 1 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 1/4, and the exit area is 0.001 m₂. The area of the suction cup is 0.1 m₂.

a. Find the velocity of the water at the exit for maximum lift condition.

b. Find the discharge through the system for maximum lift condition.

c. Find the maximum load the suction cup can support.
