### Why is pressure greater at the bottom of the pool rather than the top of the pool?

Pressure increases with depth in a fluid due to the weight of the fluid column above pressing down. This means the pressure is higher at the bottom of the pool where there is more water above compared to the top where there is less water above.

### Why are dams built stronger and broader at the bottom?

Because water pressure is more intense at depth than it is near the surface - hence the dam has to be stronger at the bottom - it withstands more pressure at the bottom.

### Is chlorinated pool water more dense than fresh water?

No, chlorinated pool water is not more dense than fresh water. Both chlorinated pool water and fresh water have a density of approximately 1 g/cm3 at standard temperature and pressure.

### Why dams must be constructed so that they are much thicker at the bottom than the top?

Because the water pressure at the bottom of the dam is much more than the top.

### Is there more pressure at the bottom of a bathtub of water 30cm deep or at a bottom of a pitcher of water 35cm deep?

The pressure at the bottom of the pitcher of water 35cm deep is higher than at the bottom of the bathtub of water 30cm deep. Pressure in a fluid increases with depth, so the deeper the water column, the greater the pressure at the bottom. This is due to the weight of the water above exerting a force on the bottom.

### Why does the bottom of a airplanes wing have high air pressure?

Because the air moving above the wing is of lower pressure than the bottom. This pressure differential is what creates lift. Check out Bernoulli's Principle for more information.

### What does but i had already swun ahead and guessed some loss much larger than i understood more danger than the deep end of the pool reveal?

If you were in a pool and swam ahead of everyone else, there could be more danger if you couldn't touch the bottom of the pool and became tired. People do not necessarily have to be in the deep end of the pool to drown.

### How much water will evaporate out of a pool on a sunny day that is 18 by 36 ft?

More than zero but less than or equal to the volume of the pool. There is insufficient information to give a more precise answer. Air and water temperatures matter, as does humidity, wind speed, color of the bottom of the pool, etc.

### Would you feel more pressure 5 m underwater in a pool or 2 m underwater in the lake?

You would feel more pressure 5 m underwater in the pool because the weight of the water above you increases with depth. The pressure in the lake at 2 m would be less than at 5 m in the pool due to the difference in water depth.

### Where will you experience greater pressure swimming in the sea or in the pool at the same depth?

You will experience greater pressure swimming in the sea than in a pool at the same depth. This is because the sea is denser than pool water, so the pressure exerted by the water due to its weight will be greater in the sea.

### Why are dams made thinner at the bottom?

This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.

### Why is the base of a dam thinner then the wall?

The pressure against the dam wall increases at the lower levels than nearer the surface. So I expect the foot of the dam wall to be thicker at the bottom than at the top.
