Mechanical Properties Of Fluids

Question

Wired Faculty App

Why two ships sailing in the same direction tend to come closer?

Solution

When two ships are moving in the same direction, the velocity of the water between the two ships increases, because area at A is greater than area at B.

Therefore, pressure in the region between the two ships decreases, and water on the outer side exerts more pressure than between two ships. Therefore, the ships tend to come closer towards each other.
