Question

Определите, с какой силой атмосферный воздух давит на горизонтальную поверхность площадью 2 м2. Нормальное атмосферное давление 760 мм рт. ст

Answer 1

1 ммртст = 133,3 Па

760 мм рт ст= 101308  Па

 

F= p S

F= 101308* 2=202616 H

Answer 2

Calculating Atmospheric Pressure

To calculate the force exerted by the atmospheric pressure on a horizontal surface, we can use the formula:

Force = Pressure × Area

Given: - Normal atmospheric pressure = 760 mmHg - Area = 2 m^2

Using the given values, we can calculate the force exerted by the atmospheric pressure on the given surface.

Calculation

The formula for converting mmHg to pascals is: 1 mmHg = 133.322 pascals.

So, 760 mmHg = 760 × 133.322 pascals.

Let's calculate the force using the formula:

Force = Pressure × Area

Force = (760 × 133.322) pascals × 2 m^2

Force = 202387.2 newtons

Therefore, the atmospheric pressure exerts a force of approximately 202387.2 newtons on the horizontal surface with an area of 2 m^2.
