Answer:
F = 23544 [N]
Explanation:
To solve this problem we must use the following expression for static pressure in fluids.
[tex]P=Ro*g*h[/tex]
where:
P = pressure [Pa]
Ro = density = 800 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = depth = 1.2 [m]
Now replacing:
[tex]P = 800*9.81*1.2\\P=9417.6 [Pa][/tex]
And the pressure is defined as the relationship of force between the area.
[tex]P=F/A\\[/tex]
where:
F = force [N]
a = area = 2.5 [m²]
[tex]F = P*A\\F = 9417.6*2.5\\F = 23544 [N][/tex]
