1) If you were to ride in an open-cockpit airplane to anelevation of 4000 ft above the sea level, what would theatmospheric pressure be if it conform to the standardatmosphere? 2) The peak of a certain mountion is 13500 ft above sea level.What is the approximate atmospheric pressure? 3)Expressed as a gage pressure, what is the pressure at thesurface of a glass of milk? 1) If you were to ride in an open-cockpit airplane to anelevation of 4000 ft above the sea level, what would theatmospheric pressure be if it conform to the standardatmosphere? 2) The peak of a certain mountion is 13500 ft above sea level.What is the approximate atmospheric pressure? 3)Expressed as a gage pressure, what is the pressure at thesurface of a glass of milk?Explanation / Answer
If you're taking fluid mechanics, check the back of yourtextbook for a table that lists the standard atmospheric pressureat various altitudes. My textbook lists standard atmospheric pressure at4000ft as 12.7194psi. At 13500 ft, 8.80874psi The gage pressure at the surface of a glass of milk would bezero. Gage pressure is actual pressure minus atmosphericpressure. Since atmospheric pressure is the only pressureacting at the surface of a glass of milk, the gage pressure iszero. Hope this is helpful.Related Questions
