Centre of pressure of a plane surface of arbitrary shape immersed vertically in a static mass of fluid________________?
Correct answer: A. Is independent of the specific weight of the fluid
- A. Is independent of the specific weight of the fluid
- B. Lies above the centroid of the plane surface
- C. Is different for different fluids
- D. Is at the centroid of the plane surface
Explanation
For a vertical plane surface, the centre of pressure lies below the centroid because pressure increases with depth. Its position depends on geometry and depth, but the specific weight cancels from the location formula.
