What speed is Mach 1 at 40000 feet?
573 knots
Mach 1 at sea level is approximately 661 knots (761 mph/ 1224 kph) and 573 knots (660 mph/ 1062 kph) at 40000 feet. Apart from the Concorde, which flew at Mach 2.0 (2 x the Speed of Sound) all of today’s modern airliners fly at sub-sonic speeds.
What is the Speed of Sound at 35000 ft?
about 660 mph
At 35,000 feet, the cruising altitude of a typical passenger jet, sound travels at about 660 mph (1,062 kmph).
What speed is mach5?
about 3,800 mph
The plane is fast, but it could have been even faster. “We settled on Mach 5 version,” says Kevin Bowcutt, Boeing’s senior technical fellow and chief scientist of hypersonics, noting that exceeding Mach 5, or about 3,800 mph, requires far more advanced engines and materials.
What speed is mach7?
Mach to Miles per hour table
| Mach | Miles per hour |
|---|---|
| 5 Mach | 3806.04 mph |
| 6 Mach | 4567.24 mph |
| 7 Mach | 5328.45 mph |
| 8 Mach | 6089.66 mph |
What is the speed of sound at 43000 feet?
Flying at 43,000 feet over the desert, the temperature would have reduced the speed of sound to around 660 mph, almost 100 mph slower than at sea level. But to break this sound barrier, Yeager needed a special plane.
What is mark20 speed?
Despite the problem, the aircraft reached speeds around Mach 20 (about 15,000 mph) and was able to control its flight for several minutes, officials said. “HTV-2 demonstrated stable, aerodynamically controlled Mach 20 hypersonic flight for approximately three minutes,” said DARPA director Regina Dugan in an Aug.
