An airplane is flying at an altitude of 2,000 m with a speed of 216 m/s. What is the pressure of air outside the plane?
To determine the pressure of air outside the plane, we can use the formula for dynamic pressure. Dynamic pressure is given by the equation:
Dynamic pressure = 0.5 * density * velocity^2
First, let's find the density of the air at the given altitude. The density of air varies with altitude due to the change in atmospheric pressure.
Next, we'll substitute the values into the formula to calculate the dynamic pressure.
Finally, we'll convert the dynamic pressure to the absolute pressure by adding the standard atmospheric pressure at sea level.
Given that the altitude is 2,000 m and the speed is 216 m/s, we can proceed with the calculations.
