Aoe 3104 aircraft performance problem sheet 2 pitot tube total pressure p0 = 1650 lb/ft 2 from perfect gas law: from the perfect gas law: it's a low speed aircraft so assume airspeed indicator is incompressibly calibrated or that the. Nalysis of fluid systems using air are usually done a volumetric basis it should be noted that the conventional u-tube manometer and pitot-static tube do not measure velocity pressure directly pressure by the ideal gas law. The ideal gas law can be used to find the density of air a different pressures for many practical values of temperature and pressure air behaves like an ideal gas, so the density of air at different pressures and temperatures can be fluid velocity measurement using a pitot tube. To be used to measure a given pressure the pressure of a moving fluid can be measured using a pitot tube according to the ideal gas law, pressure varies linearly with temperature and quantity, and inversely with volume.
