Pressure and its Measurement Fluid Pressure at a Point Fluid pressure at a point is the force exerted by the fluid per unit area at that specific point. **Example:** The pressure at the bottom of a swimming pool is higher than at the surface due to the weight of the water above. **Advantages:** - Provides a fundamental understanding of fluid behavior. - Essential for calculating forces in fluid systems. **Disadvantages:** - Can be complex to measure accurately in turbulent conditions. **Applications:** Hydraulic systems, underwater exploration, and designing dams. **Conclusion:** Understanding fluid pressure at a point is crucial for various engineering applications and helps predict fluid behaviour under different conditions. ### Pascalโs Law Pascal's Law states that any change in the pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container. **Example:** Hydraulic lifts used in car repair...
