Pressure in Fluid at Rest

When a fluid is at rest, the pressure it exerts at any point within the fluid is the same in all directions. This is known as Pascal's law. The pressure in a fluid depends on the depth of the fluid and the density of the fluid.

Pressure in a Narrow Mouth Container

In a narrow mouth container, the fluid column is restricted by the narrow opening. However, the height of the column remains the same. Since the pressure in a fluid at rest is the same at any given depth, the pressure at a certain depth from the fluid surface will be the same in a narrow mouth container.

Pressure in a Broad Mouth Container

In a broad mouth container, the fluid column has a larger cross-sectional area compared to the narrow mouth container. However, the height of the column remains the same. Since the pressure in a fluid at rest is the same at any given depth, the pressure at a certain depth from the fluid surface will also be the same in a broad mouth container.

Conclusion

Therefore, the pressure will be the same at a certain depth from the fluid surface in both the narrow mouth container and the broad mouth container. This is because the pressure in a fluid at rest depends only on the depth and density of the fluid, not on the shape or size of the container.
