To calculate the liquid pressure at points A, B, and C in the given diagram, we need to consider the height and density of the liquid.
Let's assume that the liquid in the container is water, which has a density of approximately 1000 kg/m³.
Given:
- Height of column AB = 60 cm = 0.6 m
- Height of column BC = 30 cm = 0.3 m
To calculate the pressure at each point, we can use the formula:
Pressure = density * gravity * height
where:
- Density = 1000 kg/m³ (density of water)
- Gravity = 9.8 m/s² (acceleration due to gravity)
Calculating the pressures:
At point A:
Pressure_A = density * gravity * height_AB
= 1000 kg/m³ * 9.8 m/s² * 0.6 m
= 5880 Pascal (Pa)
At point B:
Pressure_B = density * gravity * (height_AB + height_BC)
= 1000 kg/m³ * 9.8 m/s² * (0.6 m + 0.3 m)
= 8820 Pascal (Pa)
At point C:
Pressure_C = density * gravity * height_BC
= 1000 kg/m³ * 9.8 m/s² * 0.3 m
= 2940 Pascal (Pa)
Therefore, the liquid pressures at points A, B, and C are as follows:
- Pressure at point A = 5880 Pa
- Pressure at point B = 8820 Pa
- Pressure at point C = 2940 Pa
