Assignment:
If the temperature is constant then the atmospheric pressure P (in pounds/square inch) varies with the altitude above sea level h in accordance with the law
P=Poe^-kh
where Po is the atmospheric pressure at sea level and k is a constant. If the atmospheric pressure is 15 lb/in^2 at sea level and 12.5lb/in^2 at 4000 ft, find the atmospheric pressure at an altitude of 12,000 ft.
How fast is the atmospheric pressure changing with respect to altitude at an altitude of 1200ft?
Provide complete and step by step solution for the question and show calculations and use formulas.
