why deep waters run slow?????

It is mainly due to the bernoulli''s principle, which is given as

where,  - density of the medium

v-velocity of water

g-gravtatinal acceleration.

z-height below the surface

p-pressure

so, we can say that z is inversely proportional to v, thus if height increases, velocity decreases.

Dear Homanga,

It''s based on the idea that the deepest rivers and streams have the calmest surfaces. On the top they look like nothing''s happening, but below, water is flowing.

Still waters run deep means that people who have a calm or quiet exterior may have rich and interesting personalities, and may have fascinating ideas. The idea is that, if someone is quiet or seems to be slow or inattentive, they may be worth paying as much or more attention to than the person who''s talkative and vibrant.
