A swimming pool is filled with water to a height of 5m. A) what is the pressure exerted by the water on the bottom of the pool B) if a small boy swims horizontally in the pool, calculate the pressure experienced by the body when he is at I) The surface ii) half depth iii) The bottom of the pool?

A) given, h=5m g=9.81 density = 1000kg/m2
Pressure= height * gravity * density
P= 5*9.81*1000. = 49050N/m2

B) (i) in this analysis, the fluid doesn't exert any pressure on the boy. Instead, the boy's exerting pressure on the fluid . So the only pressure exerted on the boy will be atmospheric pressure which has a value of 1.01325*10^5 N/m2

(ii) half depth.
where h=5/2 = 2.5m
using previous formula P =2.5*9.81*1000 = 24525N/m2

(iii) bottom of the pool
It'll be same pressure exerted by the water on the bottom of the pool = 49050N/m2
