Where p0 is the atmospheric pressure at sea level and k is a constant. If the atmospheric pressure is 14.7 lb/in.2 at sea level and 12.6 lb/in.2 at 4,000 ft, find the atmospheric pressure at an altitude of 10,000 ft. (Round your answer to two decimal places.)

The value of pressure at an altitude of 10000 ft = 10

Step-by-step explanation:

Given data

Atmospheric pressure = 14.7

Pressure at 4000 ft = 12.6

If temperature is constant then the atmospheric pressure is varies with the altitude according to law

P (h) = ------ (1)

where k= constant & h = height

12.6 = 14.7

0.857 =

㏑ 0.857 = - 4000 k

-0.154 = - 4000 k

k = 3.85 ×

Thus the atmospheric pressure at an altitude of 10,000 ft is

14.7 × ----- (2)

Product of k & h is

k h = 3.85 × × 10000

k h = 0.385

Put his value of k h = 0.385  in equation (2) we get

14.7 ×

10

This is the value of pressure at an altitude of 10000 ft.
