The diagram shows a tank that is filled with oil. The density of the oil is 920 k g m 3 . Calculate the volume of the tank from the dimensions shown in the diagram.

length = 2 m breadth = 1 . 5 m height = 1 m Volume of tank = l × b × h Volume of tank = 2 × 1 . 5 × 1 Volume of tank = 3 m 3

The diagram shows a tank that is filled with oil. The density of the oil is 920 k g m 3 . Calculate the weight of the oil in the tank.

Density = Mass Volume . Mass = Density × Volume Density = 920 k g m 2 . Mass = 920 × 3 Mass = 2760 k g Weight = M × g Weight = 2760 × 10 Weight = 27600 N .

The diagram shows a tank that is filled with oil. The density of the oil is 920 k g m 3 . Now calculate the pressure using p = h p g . Do you find the same answer ?

Pressure p = h ρ g Height, h = 1 m Pressure, p = 1 × 920 × 10 Pressure, p = 9200 Pa Pressure in both the case is same

The diagram shows a tank that is filled with oil. The density of the oil is 920 k g m 3 . The pressure on the bottom of the tank is caused by the weight of the oil. Calculate the pressure using: P = F A .

Force exerted by bottom = Weight of object Area = 1 . 5 × 2 Area = 3 m 2 p = F A p = 920 k g × 30 m / s 2 3 m 2 p = 9200 N m 2 p = 9200 P a .
