The pressure of a fluid varies with depth h as P = PQ+pgh, where p is the fluid density. This expression is associated with Correct Answer Pascal\u2019s law

Pascal's law is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

This principle is stated mathematically as: P= P + rgh
