An oil tank has a base of area 2.5 m2 and is filled with oil to a depth of 1.2 m. The density of the oil is 800 kg/m3. What is the force exerted on the base of the tank due to the oil?
A. 960N
B. 2400N
C. 9600N
D. 24 000N

D. F = 24000[N]

Explanation:

To be able to calculate the force we must first find the pressure at the bottom of the tank. By means of the following equation:

where:

Ro = density of the liquid = 800 [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 1.2 [m]

Pressure is defined as the relationship between Force on the area.
