What is the total force on the bottom of a swimming pool 27.5m by 9.0m whose uniform depth is 1.9m? physics
What is the absolute pressure on the bottom of a swimming pool?
What will be the pressure against the side of the pool near the bottom?

Use the equation Pfluid=Density x height x gravity
(1000)(1.9)(9.8)=18,620
The TOTAL absolute pressure on the bottom and against the sides of the swimming pool is 18,620 + 1.01x10^5 = 119,620 Pa
Use the equation Pressure = Force/Area
Rearrange the equation to Force = Pressure x Area.
So, Force = 119,620 / (27.5x9) Which equals 29,605,950N. 
FINALLY. this^^ is correct.
