Machine oil is poured to the top in a 25 cm can, how much pressure does it put on the bottom of the can?

Given:

h = 25 centimeters – the height (depth) of the can;

ro = 900 kg / m3 (kilogram per cubic meter) – the density of the engine oil poured into the can;

g = 9.8 N / kg (Newton per kilogram) is the acceleration of gravity.

It is required to determine P (Pascal) – how much pressure the engine oil exerts on the bottom of the can.

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

h = 25 cm = 25 * 10-2 = 25/100 = 0.25 meters.

Then, to determine the pressure on the bottom of the can, you need to use the following formula:

P = ro * g * h;

P = 900 * 9.8 * 0.25 = 8820 * 0.25 = 2205 Pascal (approximately 2.2 kPa).

Answer: machine oil exerts a pressure on the bottom of the can equal to 2205 Pascal (approximately 2.2 kPa).
