Question

The rate of change of atmospheric pressure p with respect to altitude h is proportional to p, provided that the temperature is constant. at a specific temperature the pressure is 102.2 kpa at sea level and 87.9 kpa at h = 1,000 m. (round your answers to one decimal place.) (a) what is the pressure at an altitude of 2500 m?

Answer 1

1. Calculate the change in pressure from sea level to 1000m up. 102.2kpa-87.9kpa = 14.3kpa 2.Divide the change in pressure by 1000. 3.Then multiply by 2500. (14.3 / 1000) * 2500 = 35.8kpa. 4. Subract from the pressure at sea level. 102.2kpa - 35.8kpa = 66.4kpa.
