The speed of sound at 40000 feet is about 670 miles per hour. This is determined by the temperature and pressure of the air. The speed of sound is also affected by the humidity of the air.

What is the speed of sound at 50000 feet?
The speed of sound at 50000 feet is about Mach 2.5. This is the speed of sound at high altitudes, where the air is thinner. The speed of sound varies depending on the type of air, the temperature, and the altitude.
What is the sound barrier at 40000 feet?
There is no sound barrier at 40000 feet.
At some point in time, somebody probably decided to call the point beyond which sound cannot travel faster than the speed of sound the “sound barrier.” But the term is a misnomer. There is no physical barrier that aircraft cannot cross.
The so-called sound barrier is actually a point at which the air becomes so dense that sound waves cannot travel through it as quickly as they do in less dense air. The barrier exists because of the physical limitations of sound, not because of any man-made barrier.
The speed of sound is determined by the properties of the medium through which it travels. In a gas like the atmosphere, the speed of sound is determined by the temperature and the pressure of the gas. The higher the temperature and the higher the pressure, the faster the sound waves will travel.
At sea level, the speed of sound is about 760 miles per hour. But as an aircraft climbs higher into the atmosphere, the temperature and pressure decrease. The speed of sound also decreases as the altitude increases.
At 40000 feet, the speed of sound is about 670 miles per hour. So the sound barrier is actually a point at which the speed of sound drops below the speed of the aircraft.
What is the speed of sound at 80000 feet?
What is the speed of sound at 80000 feet?
The speed of sound at 80000 feet is about 984 mph. This is just a estimation and can change depending on weather conditions.
How fast is Mach 1 at altitude?
The speed of sound, also known as Mach 1, is a measure of how fast an object is traveling when it creates a sonic boom. This speed varies depending on the altitude and temperature of the environment.
At sea level, the speed of sound is approximately 768 miles per hour. However, this speed decreases as altitude increases. For example, at an altitude of 10,000 feet, the speed of sound is approximately 661 miles per hour. The speed of sound also decreases as temperature decreases. For example, the speed of sound is approximately 885 miles per hour at a temperature of 95 degrees Fahrenheit, but it is only 761 miles per hour at a temperature of -10 degrees Fahrenheit.
Can a 747 break the sound barrier?
The Boeing 747 is a large, four-engine jet airliner. It is the world’s most popular airliner, with more than 3,600 built since 1968.
Some people have wondered whether a 747 could break the sound barrier. But is this even possible?
The sound barrier is the point at which a vehicle traveling through the air reaches the speed of sound. This barrier was first broken by Chuck Yeager in 1947, in a Bell X-1 rocket plane.
Since then, many other aircraft have broken the sound barrier. But can a 747 do it?
There are a few factors that would make breaking the sound barrier difficult for a 747.
For one, the 747 is a large aircraft. This means that it has a lot of drag, or resistance to air flow. This resistance increases as the plane approaches the speed of sound.
In addition, the 747’s wings are not very streamlined. This means that the air flow over the wings is not very smooth. As the plane approaches the speed of sound, this air flow can create powerful shock waves.
These shock waves can cause the plane to break apart or even explode. So it is unlikely that a 747 could break the sound barrier.
What is the highest Mach ever reached?
What is the highest Mach number ever achieved?
The highest Mach number is currently Mach 6. In April of 2015, Lockheed Martin reached Mach 6 with their SR-72 Blackbird. The Blackbird is a reconnaissance aircraft that was designed and built by Lockheed Martin. The aircraft was first flown in December of 1964 and was retired in 1998. The Blackbird was able to reach Mach 6 due to its unique design.
The Blackbird has a unique design that allows it to reach high Mach numbers. The aircraft has a long and slender fuselage that is designed to reduce drag. The aircraft also has a swept wings and tail. These design features allow the aircraft to reach high speeds. The Blackbird is also equipped with engines that are designed for high speeds. The engines are a type of ramjet engine that is capable of reaching speeds of Mach 3.5.
The Blackbird is not the only aircraft that has reached Mach 6. Other aircraft have also reached this speed. However, the Blackbird is the only aircraft that has reached Mach 6 and remained in service. Other aircraft have reached Mach 6 but were retired after reaching this speed.
The Blackbird was not the first aircraft to reach Mach 6. In 1961, the X-15 reached Mach 6.5. However, the X-15 was a research aircraft and was not meant for production. The X-15 was retired in 1968.
The Blackbird is the only aircraft that has reached Mach 6 and remained in service. other aircraft have reached Mach 6 but were retired after reaching this speed.
How far can a sonic boom be heard?
The sonic boom is the sound associated with the shock waves created by an object traveling faster than the speed of sound. The sound can be heard by people and animals for miles around. The farther away from the source, the softer the sound will be.
