Same as the book problem but different values.

a suction device is being designed based on the venturi principle

to lift objucts submerged in water. the operating water temperature

is 50 c. the suction cup is located 1.3 m below the water surface,

and the venturi throat is located 1 m above the the water. the

atmospheric pressure is 100 kpa. the ratio of the throat area

(i. e., the constricted area) to the exit area is 1/4, and the exit

area is 0.001 m squared. the area of the suction cup is 0.25 m

squared.

a. find the velocity of the water at the exit for maximum lift

condition.

b. find the volume discharge through the system for maximum lift

condition.

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

state explicitly the restriction that constrains the maximum lift

(or minimum pressure in the system).
