Question

При массе 60 кг и росте 1,6 м площадь поверхности тела человека равна примерно 1,6 м2. Рассчитайте силу, с которой атмосфера давит на человека (при нормальном атмосферном давлении)!

Answer 1

P = F/S
F = p * S 
p = 101300 Па * 1.6 м^2 = 162080H = 162 кПа
Ответ: 162 кПа

Answer 2

Calculating Atmospheric Pressure on a Human

To calculate the force with which the atmosphere presses on a person at normal atmospheric pressure, we can use the formula:

Pressure = Force / Area

Given: - Mass (m) = 60 kg - Height (h) = 1.6 m - Surface area of a human body ≈ 1.6 m^2

We can calculate the force exerted by the atmosphere on the person by using the formula:

Force = Pressure × Area

First, let's calculate the surface area of the person's body.

Calculating Surface Area of the Person's Body

The surface area of a person's body can be approximated using the following formula:

Surface Area = 0.007184 × (Height in cm)^0.725 × (Mass in kg)^0.425

Let's calculate the surface area using the given mass and height.

Surface Area = 0.007184 × (160)^0.725 × (60)^0.425

Calculating Force Exerted by the Atmosphere

Now that we have the surface area, we can calculate the force exerted by the atmosphere using the formula:

Force = Pressure × Area

Given that the surface area is approximately 1.6 m^2, we can calculate the pressure exerted by the atmosphere.

Conclusion

By using the given mass, height, and the approximate surface area of a human body, we can calculate the force with which the atmosphere presses on the person at normal atmospheric pressure.
