What can be said about the water pressure at a depth of 8 cm in: a glass; a saucepan; pool; lake?

The pressure of the liquid column is determined by the formula:

P = ro * g * h, where:

P – pressure, Pascal;

ro is the density of the liquid, kilogram per cubic meter (kg / m3);

g – acceleration due to gravity, at a distance much less than the Earth’s radius; constant value equal to 9.8 m / s2;

h – depth (height of the liquid column), meter.

Since in the condition we are talking about the same liquid – water (density 1000 kg / m3), and the level is the same everywhere and is equal to h = 8 centimeters = 0.08 meters, the pressure will be the same.

Answer: in a glass, a saucepan, a pool and a lake at a depth of 8 centimeters, the water pressure will be the same.
