Aneroid barometers can be used to measure changes in altitude. If a barometer reads \(30.1 \mathrm{in}\). \(\mathrm{Hg}\) at one elevation, what has been the change in altitude in meters when the barometer reading is 28.3 in. \(\mathrm{Hg}\) ? Assume a standard atmosphere and that Eq. 2.12 is applicable over the range of altitudes of interest.
