A one-tenth-scale model of a supersonic wing tested at 700 m/s in air at 20°C and 1 atm shows a pitching moment of 0.30 kN.m. If Reynolds-number effects are negligible, what will the pitching moment of the prototype wing be flying at the same Mach number at 8- km standard altitude? For sea-level air, take p = 1.225 kg/m³ and sound speed a = 340 m/s. For air at 8000-m standard altitude, take p = 0.525 kg/m³ and sound speed a = 308 m/s. The pitching moment of the prototype is KN.m.
