Question

The atmospheric pressure above a swimming pool changes from 755 to $765 \mathrm{~mm}$ of mercury. The bottom of the pool is a rectangle $(12 \mathrm{~m} \times 24 \mathrm{~m})$. By how much does the force on the bottom of the pool increase?

The atmospheric pressure above a swimming pool changes from 755 to $765 \mathrm{~mm}$ of mercury. The bottom of the pool is a rectangle $(12 \mathrm{~m} \times 24 \mathrm{~m})$. By how much does the force on the bottom of the pool increase?



Answers

($a$) Determine the total force and the absolute pressure on the bottom of a swimming pool 28.0 m by 8.5 m whose uniform depth is 1.8 m.($b$) What will be the pressure against the $side$ of the pool near the bottom?
