In a swimming pool, where is the greatest fluid pressure?

At the bottom of swimming pool the pressure will be maximum.

Explanation:

Here as we know that pressure inside the water is given as

here we know that

= atmospheric pressure

= density of water

h = depth inside the water where pressure it to be required

So here from the above equation we know that pressure is increased as the depth inside the water is increased.

So in order to have maximum pressure inside the swimming pool we need to go at maximum depth position.

So it is at the bottom of the swimming pool pressure will be maximum.
