Awesome Pictures Of Jets Smashing The Sound Barrier U.S. Navy. For an airplane to break the sound barrier, it must hit speeds of about 770 mph — when it does that a couple of things happen. All the air in front of the craft gets pushed together, can't get out of its own way — and when that magic number gets hit — the air finally breaks free and crashes behind the plane causing a sonic boom.

- The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. The formula to find the speed of sound in air is as follows:v = 331m/s + 0.6m/s/C * T. v is the speed of sound and T is the temperature of the air.One thing to keep in mind is that this formula finds the average speed of sound for any given temperature. The speed of sound is also affected by other factors such as humidity and air pressure.he speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. The formula to find the speed of sound in air is as follows:

- subsonic: A vehicle that is traveling slower than the speed of sound (M. supersonic: sound barrier: The term sound barrier is often associated with supersonic flight. In particular, breaking the sound barrier is the process of accelerating through Mach 1 and going from subsonic to supersonic speeds.asic Definitions: speed of sound: The speed of sound is a basic property of the atmosphere that changes with temperature. For a given set of conditions, the speed of sound defines the velocity at which sound waves travel through a substance, such as air.

What happens when an aircraft breaks the sound barrier? As the local temperature decreases, the sound speed also decreases, so for a plane flying at 35,000 feet¿where the ambient temperature is ¿54 C¿the local speed of sound is 295 meters per second (660 miles per hour).

Supersonic speed In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities. Supersonic fracture is crack motion faster than the speed of sound in a brittle material.

Supersonic Speed Demons: Breaking the Sound Barrier On Oct. 1, 1969, the Concorde 001, a joint British-French venture, traveled faster than the speed of sound for the very first time. It was the aircraft's 45th test flight and it held Mach 1.05 for 9 minutes at 36,000 feet and 75 miles from Toulouse, France.

How many feet per second is the speed of sound? I read up a little bit on the speed of sound, and I understand that it changes depending on medium pressure (?) and thus decreases with altitude in air. 761 mph is the speed of sound at sea level, but at 11000+ feet, it's 660 mph. I'm using the 761 mph number to do my math. 761 miles = 4018080 feet 1 hour = 3600 seconds Speed of sound at sea level = ~1116.13 feet per second Are those correct calculations? jmm

- Story highlights. 1  Special forces 'want to be sneakier with slower, quieter bullets'. 2  The quieter bullets would travel slowly enough not to break the sound barrier. 3  Bullets that travel 1,100 feet per second at sea level make a crack! sound.  Subsonic bullets do, however, pose a greater risk of jamming.

speed of sound Part of the IT standards and organizations glossary: The speed of sound, or of acoustic traveling waves, is a physical constant for any given medium at a specific pressure and temperature. In dry air at sea level at 0 degrees Celsius, the speed of sound is approximately 331.4 meter s per second (m/s). Temperature, pressure, and humidity affect this value to some extent.

Sound barrier In dry air at 20 °C (68 °F), the sound barrier is reached when an object moves at a speed of 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s). The term came into use in this sense during World War II, when a number of aircraft started to encounter the effects of compressibility, a number of unrelated aerodynamic effects that struck their aircraft, seemingly impeding further acceleration.

Speed of sound The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or a kilometre in 2.91 s or a mile in 4.69 s. The speed of sound in an ideal gas depends only on its temperature and composition.

Speed of Sound in Air The speed of sound in air is approximately 331.5 m/s at 0 °C or around 1200 km per hour. The speed of sound through air is approximately 343 m/s at normal room temperature, which is at 20 °C. The speed of sound through air is 346 m/s at 25 °C. The speed of sound in air is approximately figured out by the formula ….

Sound barrier At speeds of 950 to 1,000 km/h (590 to 620 mph) the air flow around the aircraft reaches the speed of sound, and it is reported that the control surfaces no longer affect the direction of flight. The results vary with different airplanes: some wing over and dive while others dive gradually.

- Slower. Nothing goes faster than light, which travels at a speed of 300.000 km/second, or 186.000 miles/second. Sound travels through our air at the speed of about 343 metres/ … second, or 0,343 km/second, which is 1.125 feet/second, which is in its turn about 0,213 miles/second.

What is the Speed of Sound? At a temperature of 32-degrees Fahrenheit (0 Celsius) the speed of sound drops to 742 mph (1,194 km/p/h). In altitudes above sea level the speed of sound is again different and will vary depending on prevailing factors. The reason for this variance is that sound waves travel by exciting molecules.

Chuck Yeager retraces history in the sky, breaking the sound barrier -- again I really appreciated the Air Force giving me a brand new F-15 to fly, Yeager told CNN. Today, fighter jets can easily break the sound barrier. In fact, Yeager's flight Sunday did it at an altitude of about 33,000 feet, according to a statement provided by the Air Force.

What Is the Speed of Sound? The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h).

Supersonic Speed Demons: Breaking the Sound Barrier The Myth of the 'Sound Barrier'. As pilots approached the speed of sound (which varies depending on the type of medium and the temperature of the medium), they would encounter control issues, he said. There were a lot of near crashes and incidents associated with flying near the speed of sound, he said.

The Speed of Sound VS. The Speed of Light Even though sound isn't as fast as light the speed sound travels at isn't exactly slow. Something that travels at 761 miles per hour is still pretty fast. Objects such as planes that go faster than the speed of sound (761 mph) travel at Mach 1. Objects that travel 2 times the speed of sound (1522 mph) travel at mach 2. When traveling faster than the speed of sound objects create something known as a sonic boom.

The Speed of Sound In equation form, this is. The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s. A slower wave would cover less distance-perhaps 660 meters-in the same time period of 2 seconds and thus have a speed of 330 m/s. Faster waves cover more distance in the same period of time.

What is the Speed of Sound? These 10 facts about space will blow your mind. The speed of sound varies depending on altitude, temperature and the medium through which it travels. For example, at sea level in a standard atmosphere, at a temperature of 59-degrees Fahrenheit (15 Celsius), sound travels 761 miles per hour (1,225 km/p/h).
