calculate pressure on surface of tank of 3*2*2 cm if it is half filled
To calculate the pressure on the surface of a tank, we need to know the density of the liquid, the depth of the liquid, and the acceleration due to gravity.
Given that the tank has a dimension of 3*2*2 cm and is half-filled, we first need to calculate the depth of the liquid. Since it is half-filled, the depth would be half of the height of the tank, which is 2 cm divided by 2, giving us a depth of 1 cm.
Next, we need to know the density of the liquid. Let's assume it is water, which has a density of approximately 1000 kg/m³.
Now, we can calculate the pressure using the formula:
Pressure = Density × Gravity × Height
First, we need to convert the dimensions to meters, as the density is given in kg/m³:
Height = 2 cm = 2/100 m = 0.02 m.
Now we can calculate the pressure:
Pressure = 1000 kg/m³ × 9.8 m/s² × 0.02 m = 196 Pascal (Pa).
Therefore, the pressure on the surface of the tank is 196 Pa.
