A 50 cm high bottle is filled with water. Determine the pressure of only the column of water at the bottom of the bottle.

By the conditions of the problem, we have:

h = 50 cm = 0.5 m – the height of the water column;

p = 1000 kg / m ^ 3 – water density;

g = 9.8 m / s ^ 2 – acceleration of gravity.

The pressure of the water column at the bottom of the bottle is found by the formula:

P = p * g * h = 0.5 * 1000 * 9.8 = 4900 Pa.

Answer: the water pressure at the bottom of the bottle is 4900 Pa.
