Here is a plot of the speed of sound at different heights above sea level. At sea level, the value is right around the 340 m/s mark. If you move up to 120,000 feet, the speed will drop down to.. The speed of sound is not a constant, but depends on altitude (or actually the temperature at that altitude). A plane flying Mach 1.0 at sea level is flying about 1225 km/h (661 Knots, 761 mph), a plane flying Mach 1.0 at 30000 ft is flying 1091 km/h (589 knots, 678 mph) etc. Speeds below Mach 1 are called subsonic, between Mach 0.8-1.2 Transonic and above Mach 1.2 Supersonic Speed of Sound table chart including Speed of Sound at a known temperature and density of air, Speed of Sound vs Density of Air .

Supersonic speed is the speed of an object that exceeds the speed of sound. For objects traveling in dry air of a temperature of 20 °C at sea level, this speed is approximately 343.2 m/s. Speeds greater than five times the speed of sound are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds ar * The speed of sound is 343 m/s or 1126*.547 ft/s (768.095 mph) at a temperature of 20°C or 68°F. The speed of sound has nothing to do with the atmospheric pressure at sea level, but the temperature..

Calc. Air pressure at sea level is 30 inches of mercury Sound travels at 1530 meters per second in ocean water. It takes 3 seconds for a sound wave to travel from the bottom of the ocean to sea level. So every second, the sound travels 1530 meters..

At sea level, at a temperature of 21 degrees Celsius (70 degrees Fahrenheit) and under normal atmospheric conditions, the speed of sound is 344 m/s (1238 km/h or 770 mph). The speed varies.. In dry, sea level air that is around 25 degrees Celsius, Mach 1 is equal to 340.29 meters per second, or 1,122.96 feet per second. Mach 1 rises with the density of the medium. In 25-degree Celsius fresh water, sound propagates at 4,940.1 feet per second. In sea water Mach 1 is equal to 5,148 feet per second, or nearly 3,600 miles per hour The speed of sound at sea level is 340 m/s. Assuming that there is a point sound source 10 m away from the closer ear and the distance between the two ears is 20 cm. The sound level of the source measured at a source - microphone distance of 1 m is 80 dB As the speed of an aircraft approaches the speed of sound, the flight Mach number is nearly equal to one (M = 1), At sea level the Mach No = (Speed of aircraft) divided by (Speed of sound). On an average day the speed of sound is 761 mph. So an aircraft travelling at sea level, at a speed of 500 MPH, would be flying at 500/761 = Mach 0.6

- Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how much distance such a wave travels in a given amount of time. In dry air with a temperature of 21 °C (70 °F) the speed of sound is 344 m/s (1230 km/h, or 770 mph, or 1130 ft/s).Although it is commonly used to refer specifically to air, the speed of sound can be measured in virtually any.
- Near and beyond the speed of sound, about 330 m/s or 760 mph at sea level, small disturbances in the flow are transmitted to other locations isentropically or with constant entropy. Sharp disturbances generate shock waves that affect both the lift and drag of the aircraft, and the flow conditions downstream of the shock wave
- Sound travels about 1500 meters per second in seawater. Sound travels much more slowly in air, at about 340 meters per second. The speed of sound in seawater is not a constant value. It varies by a small amount (a few percent) from place to place, season to season, morning to evening, and with water depth
- The speed of sound in sea water is, on average, about 1560 m/s, or 3490 mph. Compare this to the speed of sound in air, which is 343.2 m/s. The discrepancy is obvious: sound travels nearly five times faster in seawater than in dry air

Current world land speed record. 16,250 mph. Re-entry speed of a space shuttle. 25,200 mph. Earth's escape velocity. 670,616,629. ** speed of light Symbol: c **.The constant speed at which light and other electromagnetic radiation travels in a vacuum. It is equal to 299 792 458 m s -1 (value adopted by the IAU in 1976). Since space is not a perfect vacuum, radiation travels through space at a very slightly lower speed, which decreases somewhat when the radiation enters the Earth's atmosphere

Answers: See below. The equation which relates the intensity of a sound wave to its decibel level is: dB = 10 * log( I / 1.0 x 10-12 W/m 2) . where I = intensity of the sound in units of W/m 2.Using this equation, parts a - d can be computed in straightforward fashion The speed of sound calculated from this formula can be used with the equation on the first page to obtain Mach number. This equation uses the standard sea level temperature of 59 E F and a lapse rate of -3.57 E/1000 ft altitude. Temperature stabilizes at -69.7 E F at 36,000 ft so the speed of sound stabilizes there at 573 knots ** S peed of S ound From the user, an air temperature (T ) is given**. Before calculating the speed of sound, the air temperature value must be converted to Kelvin (K ). To convert the air temperature to Kelvin, see the link below: Temperature Conversion Just a side note before calculating the speed of sound, in the Earth's atmosphere, th There is no need to consider values of V e,c > 300 m/s because that speed corresponds to M 0 = 0.88 at sea level and M 0 > 1 in the stratosphere. The values of c j shown are consistent with actual values for turbofans under static, often called takeoff, conditions. Note that dividing c j in the units shown by g = 9.807 m/s 2 will yield c j in. The speed of sound changes with air temperature, humidity, and even air quality. Neither humidity nor air quality make enough of a difference to figure into PING))) sensor distance calculations. Air temperature, on the other hand, can cause measurable distance errors. The speed of sound increases by 0.6 meters per second (m/s) for every degree.

Repeat your measurements by increasing the water level in the tube. Measure the length of the air column for each resonance from the top edge of the tube. Find the difference in length (Δ L) between the two consecutive resonances to calculate the wavelength of the sound wave. Once the wavelength is determined, the speed of sound follows from. Trend data source, speeds for 737-800. The aircraft climbs at 250 KIAS from sea level. An acceleration from 250 to 300 KIAS is included at 10,000 feet. You can see that as IAS is held constant, TAS (True Airspeed) and Mach both increase. The switch from 300 KIAS to Mach 0.76 is done at FL280. You can see the Mach speed is approaching its M MO Speed-o'-Sound Sonic (音速のソニック, Onsoku no Sonikku), more commonly called Sonic, is a recurring villain and occasional anti-hero.
