The height of the column of kerosene in a kerosene lamp is 5 cm. What is the pressure of the liquid exerted on one lamp by the density of kerosene 800 kg / m ^ 3

Given:

h = 5 centimeters – the height of the column of kerosene in the lamp;

g = 10 meters per second squared – gravitational acceleration (constant near the earth’s surface);

ro = 800 kilograms per cubic meter – the density of kerosene.

It is required to determine P (Pascal) – the pressure of the column of kerosene at the bottom of the kerosene lamp.

Let’s convert the units of measurement of length from centimeters to meters:

h = 5 cm = 5 * 10-2 = 0.05 meters.

Then the pressure of the column of kerosene is determined by the following formula:

P = ro * g * h = 800 * 10 * 0.05 = 8000 * 0.05 = 400 Pascal.

Answer: the pressure of a column of kerosene is 400 Pascal.
