Question

Представь, что ты летишь на самолёте. Пилот объявил, что давление за бортом 220 мм. рт. ст. На какой высоте находится самолёт? пжшка помогите срочно

Answer 1

Відповідь:

5400 м

Пояснення:

На каждые 100 м давление изменяется на 10 мм рт. ст.

Найдем разницу  давлений между самолетом и уровнем моря:

1) 760 мм рт. ст. - 220 мм рт. ст. = 540 мм рт. ст.

2) 540 мм рт. ст. : 10 мм рт. ст. = 54

3) 54 · 100 м = 5400 м

Answer 2

Altitude Calculation Based on Atmospheric Pressure

To calculate the altitude based on the given atmospheric pressure, we can use the standard atmospheric pressure at sea level, which is 1013.25 millibars (mb) or 29.92 inches of mercury (inHg). The relationship between atmospheric pressure and altitude is inversely proportional, meaning as altitude increases, atmospheric pressure decreases.

Given: - Atmospheric pressure outside the aircraft: 220 mm Hg

To calculate the altitude, we can use the following approximate conversion: - 1 inch of mercury (inHg) ≈ 25.4 millimeters of mercury (mm Hg)

Calculation

First, let's convert the given atmospheric pressure from millimeters of mercury (mm Hg) to inches of mercury (inHg): - 220 mm Hg ≈ (220 / 25.4) inHg ≈ 8.66 inHg

Now, we can use the standard atmospheric pressure at sea level (29.92 inHg) to calculate the altitude using the formula: - Altitude = 44330 * (1 - (P / 1013.25)^0.1906) feet where P is the atmospheric pressure in mb

Altitude Calculation

Plugging in the values: - Altitude ≈ 44330 * (1 - (8.66 / 29.92)^0.1906) feet - Altitude ≈ 44330 * (1 - 0.289) feet - Altitude ≈ 31570 feet

Therefore, based on the given atmospheric pressure of 220 mm Hg, the aircraft is approximately 31570 feet above sea level.
