Question

При выкачивании нефти трубу переместили с глубины 10 м на 80 м. Как и на сколько изменилось давление нефти на трубу? ​

Answer 1

Ответ:

(80-10)×2=140

Объяснение:

когда мы начинаем перемещать трубу давление изменяется на 2 процентов и когда мы будем решать получается умножаем на 2

Answer 2

Changes in Oil Pressure due to Moving the Pipe

When a pipe is moved from a depth of 10 meters to a depth of 80 meters during oil extraction, the pressure exerted by the oil on the pipe will change. To determine how and by how much the oil pressure on the pipe has changed, we need to consider the principles of fluid mechanics.

According to Pascal's law, the pressure in a fluid is transmitted equally in all directions. This means that the pressure exerted by the oil at a certain depth is the same in all directions, including horizontally along the pipe.

When the pipe is moved from a depth of 10 meters to 80 meters, the pressure exerted by the oil on the pipe will increase. The increase in pressure is directly proportional to the depth of the oil column above the pipe.

To calculate the change in pressure, we can use the formula:

Change in Pressure = Density of Oil x Acceleration due to Gravity x Change in Depth

The density of oil can vary depending on the type of oil being extracted, but for the purposes of this explanation, let's assume a typical value of 850 kg/m³. The acceleration due to gravity is approximately 9.8 m/s².

Using these values, we can calculate the change in pressure:

Change in Pressure = 850 kg/m³ x 9.8 m/s² x (80 m - 10 m)

Calculating this, we find that the change in pressure is approximately 63,700 Pascal (Pa).

Therefore, when the pipe is moved from a depth of 10 meters to 80 meters during oil extraction, the pressure exerted by the oil on the pipe increases by approximately 63,700 Pa.

Please note that the actual change in pressure may vary depending on factors such as the density of the oil and the specific conditions of the oil extraction process.
