Question

Consider an airplane flying at a pressure altitude of 31500 ft and a density altitude of 28000 ft. calculate the outside air temperature. (round the final answer to the nearest whole number.)

Answer 1

its already roundeed to the nearest number beacuse the place holders make it value

Answer 2

Answer:

1° C

Explanation:

Thinking process:

The expression for the temperature of air in terms of the density is given as follows:

T = $\frac{P }{\rho R }$

where $\rho$ is the density of air

P is the pressure of the air

R is the characteristic gas constant

pressure of air at 31500 ft  ≈ 23 800 Pa

Thus:

T = $\frac{23.800Pa}{1.225* 287.05}$

  = 1°
