Chapter 3, Problem 37P
If atmospheric pressure at the ground is 101.3 kPa and temperature is 15°C, calculate the pressure 7.62 km above the ground, assuming (a) no density variation, (b) isothermal variation of density with pressure, and (c) adiabatic variation of density with pressure.

The basic barometer can be used as an altitude measuring device in
airplanes. The ground control reports a barometric reading of 753mmHg
while the pilot's reading is 690mmHg. Estimate the altitude of the plane
from ground level if the average air density is 1.20 kg.m-3 and the
barometer fluid is mercury, PHg=13600 kg.m3.
To solve this problem determine the atmospheric pressure on the ground
and then in the air using the barometric pressure readings.
Then using the pressure difference between the ground and the plane, the
altitude can be derived by considering a column of air from the ground up
to the plane, of constant density, in a similar manner to the barometer.
