Question 1: Why does an ocean liner float?

E. Remember the Titanic -ocean liners do not float.

Question 2: Water flows steadily from an open tank as shown in the figure. (Figure 1) The elevation of point 1 is10.0 m , and the elevation of points 2 and 3 is2.00 m . The cross-sectional area at point 2 is4.80×102 m2 ; at point 3, where the water is discharged, it is 1.60×102 m2 . The cross-sectional area of the tank is very large compared with the cross-sectional area of the pipe.

What is the gauge pressure pgaugeat point 2?Express your answer numerically in pascals.

A. It is made of steel, which floats. B. It is held up in the water by large Styrofoam compartments. C. The average density of the ocean liner is less than that of seawater. D. Its very big size changes the way water supports it.

Explanation / Answer

1)

for an object to float in water ,

the buoyant force acting on the object must be greater than weight of the object.

the weight of water displaced by the object must be greater than or equal to weight of object,

which means that the density of object must be lower than the fluid .

Hence , for ocean liner to float,

C.   The average density of the ocean liner is less than that of seawater.
