5.35 Subsonic aircraft use a pitot tube (impact pressure tube)and a static pressure port to determine aircraft airspeedby U =2ApPair2PH₂8H=where H = Aр/Pнg isPairthe differential pressure expressed in either inches Hgor mm Hg. The value of H can be measured to within1% (95%) uncertainty. For a measured H of 20 mm Hg,estimate the airspeed and the uncertainty in airspeed at sealevel due to H. Use International Standard Atmosphere(ISA) conditions of 15°C and 101,320 Pa abs. For thedensities, use PH₂(kg/m³) = 13595-2.57(°C) ±0.1and treat dry air as an ideal gas so that pair (kg/m³)3.4837 x 10³p(Pa abs)/T(K) ± 0.001. Neglect theuncertainties in the two densities in the analysis.=

Wind tunnel test section km/h Model FD Moving belt Drag balance The aerodynamic drag of a new Volvo FH truck is to be predicted at a speed of 85 km/h at an air temperature of 25°C (p=1.184 kg/m³, u=1.849x10-5kg/m-s). Volvo engineers build a 1/2 scale model of the FH to test in a wind tunnel. The temperature of the wind tunnel is also 25°C. The drag force is measured with a drag balance, and the moving belt is used to simulate the moving ground. Determine how fast the engineers should run the wind tunnel to achieve similarity between the model and the prototype.
