4. A swimming pool of width 9.0 m and length 24.0 m is filled with water to a depth of 3.0 m.Calculate pressure on the bottom of the pool due to the water.



Pressure at bottom is equal to the sum of atmospheric pressure and product of density of liquid, acceleration due to gravity and depth of container.
P= P(atm) + dgh
P = 101000 Pa + 1000*10*3
P =101000+30000
P= 131000 Pa.
