What pressure does milk put on the bottom of the glass if the depth is 12 cm, and milk is half

What pressure does milk put on the bottom of the glass if the depth is 12 cm, and milk is half [Density = 800 kg / m ^ 3]

Given:

ro = 800 kilograms per cubic meter – milk density;

h = 12 centimeters – the height (depth) of the glass.

It is required to determine P (Pascal) – how much pressure the milk exerts on the bottom of the glass.

We translate the units of measurement of length into the SI system:

h = 12 centimeters = 12 * 10-2 = 12/100 = 0.12 meters.

Since, according to the condition of the tasks, the glass is half full, then the height of the milk column is equal to:

h1 = h / 2 = 0.12 / 2 = 0.06 meters.

To determine the pressure, you must use the following formula:

P = ro * h * g (where g = 10 Newton / kilogram, approximate value).

P = 800 * 0.06 * 10;

P = 800 * 0.06;

P = 48 Pascal.

Answer: the milk exerts a pressure of 48 Pascals on the bottom of the glass.
