Question

На шахте им Костенко, расположеной в г. Караганды , горные работы ведутся на глубине более 840 м. Определите атмосферное давление на этой глубине.

Answer 1

Решение:
р= плотность*gh=>13600*9,8*840=
=111955200 Па
Атм.давление= р/133,3=111955200/133,3=839873мм рт.ст. Ответ:839873 и выше

Answer 2

Determining Atmospheric Pressure at a Depth of 840m in the Kostyanko Mine, Karaganda

To determine the atmospheric pressure at a depth of more than 840m in the Kostyanko Mine located in Karaganda, we can use the hydrostatic pressure formula, which states that the pressure at any point in a fluid at rest is equal to the weight of the fluid column above that point.

The formula for hydrostatic pressure is:

P = ρgh

Where: - P is the pressure - ρ is the density of the fluid - g is the acceleration due to gravity - h is the height of the fluid column

Given that the density of air is approximately 1.225 kg/m³ at sea level and the acceleration due to gravity is approximately 9.81 m/s², we can calculate the atmospheric pressure at a depth of 840m.

Using the formula, the atmospheric pressure at a depth of 840m can be calculated as follows:

P = ρgh P = (1.225 kg/m³) * (9.81 m/s²) * (840m)

Let's calculate the atmospheric pressure at this depth.
