You wish to use a barometer to determine your elevation above sea-level. Local weather reports indicate that the temperature is 85°F and sea-level pressure is 30.25 inHg. If your barometer reads a pressure of 22.4 inHg, what is your elevation above sea level? Assume a temperature lapse-rate of m = 0.00357°F/ft, and a linear temperature-altitude relationship (T = T0 − mz).
