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. ### Pascal’s 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 shops. **Advan
