Determine with what force the air presses on the surface of the lid of the box with an area of 0.32 m2

Determine with what force the air presses on the surface of the lid of the box with an area of 0.32 m2. (take atmospheric pressure as 1013 hPa) Express the answer in kiloNewtons.

Given:

s = 0.32 m2 (square meters) – box lid area;

P = 10 ^ 13 hPa – the value of atmospheric pressure.

It is required to determine F (kilonewton) – with what force the atmosphere presses on the box lid.

Let’s convert the units of measurement of pressure to the SI system:

P = 1013 hPa = 1013 * 10 ^ 2 = 101300 Pascal.

Then, to determine the strength, you must use the following formula:

P = F / s, from here we find that:

F = P * s = 101300 * 0.32 = 32416 Newtons = 32.416 kN.

Answer: air presses on the surface of the box lid with a force equal to 32.416 kN.
