Question

Calculating If the average or normal temperature decrease with altitude in the troposphere is 6.5°C/km, calculate the approximate altitude in which a pilot would expect to find each of the following atmospheric temperatures, if the surface temperature is 27°C. Show your work. 10°C: 0°C: meters meters

Answer 1

Answer:

- The temperature of 10°C will be experienced at an altitude of 2.52 km

- The temperature of 0°C will be experienced at an altitude of 4.15 km

Explanation:

Lapse Rate = -6.5°C/km of ascent.

Lapse Rate = Temperature difference/altitude difference

For the 10°C,

Temperature difference = 10 - 27 = -17°C

-6.5 = -17/(difference in altitude between the two points)

Difference in altitude = 17/6.5 = 2.52 km

For 0°C,

Temperature difference = 0 - 27 = - 27°C

-6.5 = -27/(difference in altitude between the two points)

Altitude difference = 27/6.5 = 4.15 km
