Centre of Pressure for a Vertical Plane Submerged Surface
The centre of pressure for a vertical plane submerged surface is the point at which the total hydrostatic force acting on the surface can be considered to act. This force is the result of the pressure distribution across the surface.
Understanding Centre of Gravity
The centre of gravity (CG) of a body is the point at which the entire weight of the body can be considered to act. It is the average position of the weight distribution.
Relations between Centre of Pressure and Centre of Gravity
In general, the centre of pressure and the centre of gravity do not coincide for a submerged surface. The relationship between the two can be explained as follows:
1. Centre of Pressure below Centre of Gravity: In most cases, the centre of pressure for a submerged surface is located below the centre of gravity. This is because the hydrostatic force acting on the surface increases with depth. As a result, the resultant force is higher at the lower portion of the surface, leading to a centre of pressure below the centre of gravity.
2. Centre of Pressure above Centre of Gravity: However, there are no cases where the centre of pressure for a vertical plane submerged surface can be above the centre of gravity. This is because the hydrostatic pressure always increases with depth, causing the resultant force to act in a downward direction. Therefore, the centre of pressure is always below the centre of gravity.
Conclusion
In conclusion, the centre of pressure for a vertical plane submerged surface is never above the centre of gravity. It can be below the centre of gravity in most cases, but it can never be above.
