Mach Speed کا حساب کیسے لگائیں

Mach Speed کیا ہے؟

Mach number is the ratio of object speed to the local speed of sound. At sea level (15°C), Mach 1 ≈ 340 m/s (1,225 km/h). The speed of sound decreases with altitude and temperature.

فارمولا

Mach number = Speed / Speed of sound | Mach 1 ≈ 343 m/s (20°C, sea level) | Speed of sound varies with temperature

1Speed of sound in air = 331.3 × √(1 + T°C/273.15) m/s
2Speed = Mach × Speed of sound
3Subsonic: < Mach 1; Supersonic: > Mach 1; Hypersonic: > Mach 5
4At 11,000m altitude: sound speed ≈ 295 m/s
