With what force atmospheric air exerts pressure on the surface of a 16×20 cm notebook sheet at normal

With what force atmospheric air exerts pressure on the surface of a 16×20 cm notebook sheet at normal atmospheric pressure p = 101300.

Given:

a = 16 centimeters = 0.16 meters – the width of the notebook sheet;

b = 20 centimeters = 0.2 meters – the length of the notebook sheet;

P = 101300 Pascal – normal atmospheric pressure.

It is required to determine F (Newton) – with what force the atmosphere will press on the surface of the sheet.

Since the notebook sheet has the geometric shape of a rectangle, its area will be equal to:

S = a * b = 0.16 * 0.2 = 0.032 square meters.

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

F = P * s;

F = 101300 * 0.032 = 3241.6 Newtons.

Answer: the atmosphere presses on the notebook sheet with a force equal to 3241.6 Newtons.
