The basic barometer can be used as an altitude measuring device inairplanes. The ground control reports a barometric reading of 753mmHgwhile the pilot's reading is 690mmHg. Estimate the altitude of the planefrom ground level if the average air density is 1.20 kg.m-3 and thebarometer fluid is mercury, PHg=13600 kg.m3.To solve this problem determine the atmospheric pressure on the groundand then in the air using the barometric pressure readings.Then using the pressure difference between the ground and the plane, thealtitude can be derived by considering a column of air from the ground upto the plane, of constant density, in a similar manner to the barometer.[h=714m]

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.m³ and the barometer fluid is mercury, PHg=13600 kg.m-³.

Some manometers are constructed as in Fig. , whereone side is a large reservoir (diameter D ) and the other sideis a small tube of diameter d , open to the atmosphere. Insuch a case, the height of manometer liquid on the reservoirside does not change appreciably. This has the advantagethat only one height needs to be measured rather than two.The manometer liquid has density ρ m while the air has densityρ a . Ignore the effects of surface tension. When there isno pressure difference across the manometer, the elevationson both sides are the same, as indicated by the dashedline. Height h is measured from the zero pressure level asshown. ( a ) When a high pressure is applied to the left side,the manometer liquid in the large reservoir goes down,while that in the tube at the right goes up to conserve mass.Write an exact expression for p 1gage , taking into account themovement of the surface of the reservoir.
