An aircraft cruises at an altitude of 10,700 meters above sea level. Estimate the atmospheric pressure in bar at cruise altitude. Assume the acceleration of gravity is constant at g = 9.8 m/s". The average specific volume of the air is 1.334 m®/kg.

Answer:

We can calculate the atmospheric pressure using the given formula:

[tex]P = P_{o} - \rho\times g\times h[/tex]

where;

[tex]P_{o} = 1.013 \times 10^{5} pa[/tex]

[tex]\rho = \frac{1}{V}[/tex]

[tex]\rho = \frac{1}{1.334} = 0.75 kg/m^{3}[/tex]

h = 10,700 m

equating the following variables in above equation, we get;

[tex]P = 1.013\times 10^{5} - 0.75 \times 9.8 \times 10700[/tex]

P = 0.227 bar
