SUMMARY
The formula P = Depth * 0.1 is not an accurate method for determining water pressure at various depths. The discussion highlights that this formula oversimplifies the relationship between pressure and depth by neglecting the mass of the fluid and the area of application. A more accurate formula is provided: P = P0 + ρ * g * h, where P0 is the initial pressure (1 bar), ρ is the density of water (1000 kg/m³), g is the acceleration due to gravity (9.81 m/s²), and h is the depth. This formula yields a more precise calculation of pressure, demonstrating that the original formula is crude and inadequate.
