Figure 2 below shows water at a dam. The depth of the water at the dam is
20 meters. The area of the wall of the dam which is in contact with the water
is 500 m 2. The atmospheric pressure is 1 atmosphere and the mass per unit
volume density of the water is 1000 kg/m^3 Find the total force exerted on the wall which is in contact with the water.
so far I've found p=2.97e5
p=1.013e5+1000*9.8*20
p=F/A
F=2.97e5*500
F=1.485e8
i found avg pressure : (1.013e5+2.97e5)/2
=1.991e5
Im not sure what to do next please help
