It is a wrong assumption that the speed of sound decreases with altitude above sea level, because the density of air decreases with height. Speed can be thought of as the rate at which an object covers distance. Hello, Can someone comment on WHERE a supersonic bullet actually breaks the sound barrier? Does this happen while the bullet is still traveling Play 100s free Online FPS Games flash or 3D shockwave games including multiplayer FPS Games games CAS/Mach/TAS/EAS Conversions. The following will calculate three speeds based on the altitude and entered fourth speed - e.g. CAS/Mach/EAS based on Altitude and TAS. Unit Descriptions; 1 Mach Number: The ratio of the speed of an object moving through a fluid to the speed of sound in the same fluid. And of course, this thing is absurdly fast. Its capable of firing off full-resolution 24-megapixel JPEGs at a blistering 20 frames per second.

The temperature indication, however, is absolutely necessary. The speed of sound at 20 degrees Celsius (68 degrees Fahrenheit) is 343 meters per second. The speed of sound at sea level under standard atmospheric conditions when the temperature is 70 degrees Fahrenheit (equivalent to 21 degrees Celsius) is 1,238 kph (kilometers per hour). In other units, this speed is equal to 770 mph (miles per hour) or 344 m/s (meters per second). 1128 fps is the exact answer at sea level at 70 degrees F. since the speed of sound is 761 mph at sea level. if you multiply 761 by 5280 (feet per mile) and divide by 3600 (seconds per hour) you get 1116.3 feet/sec. as an example, the barrett m95 .50 cal. has a muzzle velocity of 2800 fps. This on the web one-way conversion tool converts speed and velocity units from speed of sound ( sea level ) into feet per second ( ft/sec ) instantly online. The speed of sound varies depending on the type of medium through which it moves, explains Livescience. Speed of sound fps at sea level. Scholarly Search Engine Find information about academic papers by weblogr.com. Speed of sound fps at sea level 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). Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air. 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 travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 C (68 F) at sea level, this speed is approximately 343 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Probably the most important value to remember, however, is the speed of sound at sea level. GameTrailers is your destination to see official trailers first. Metacritic Game Reviews, Battlefield 1 for PC, Intuitive destruction and dynamic weather ensure that no battle is ever the same.
