The atmospheric pressure above a swimming pool changes from 755 to 765 mm of mercury. The bottom of the pool is a rectangle (12 m x 24 m). By how much does the force on the bottom of the pool (in newtons) increase? (You may consider the conversion factor: 133 Pa = 1.0 mm Hg)
Full or empty doesn’t matter. Think if the pressure went to 0, the water would boil off, because most all the pressure would disappear (except for the gravitational pressure including the water).
1 pascal = 1N/M^2
133 newtons per square meter of pool surface. figure it out.
The pressure at the top of the pool changes by 133xthe area of the top of the water (which NO I will not calculate for you)
The pressure at the bottom of the pool changes this same amount.
