SUMMARY
The discussion clarifies the appropriate use of the hydrostatic pressure equations p = ρ.g.h and p = ρ.g.hcg. The first equation is used when measuring pressure at a specific depth, where h represents the height of the water column. The second equation is applicable when calculating pressure at the center of gravity of a submerged body, where hcg denotes the distance from the water surface to the center of gravity. Understanding the distinction between 'height' and 'center of pressure' is crucial for accurate hydrostatic calculations.
