Problem 45P

An airplane is flying at an altitude of 12.000 m. Determine the gage pressure at the stagnation point on the nose of the plane if the speed of the plane is 300 km/h. How would you solve this problem if the speed were 1050 km/h? Explain.

Step-by-Step Solution:

ANSWER:

Step 1:-

The given data are,                

        

        .        

        

        Speed of the plane is, .

        The density of air at this given height is, .

        The 2nd point is at stagnation point, so .

        .

Step 2:-

        The Bernoulli’s equation for this case is,

        --------------(1)

        

        

        .

Conclusion:

        The gauge pressure will be 1079 Pa.
