What is speed of sound in air in km per hour?
The term is commonly used to refer specifically to the speed of sound in air. 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).
What is the speed of sound at 10 km?
Speed of Sound at a known temperature and density of air
| Altitude | Speed of Sound | |
|---|---|---|
| Feet (ft) | Meter (m) | km/h |
| 0 (sea level) | 0 (sea level) | 1,225 |
| 5,000 | 1524 | 1,204 |
| 10,000 | 3048 | 1,182 |
How fast is Mach 1km?

| 2 Mach | 2450.09 kph |
| 3 Mach | 3675.13 kph |
| 4 Mach | 4900.18 kph |
How many kilometers does sound travel 4 hours?
The answer you get should be 4939.2 km.
What is the speed of sound at 85000 feet?
2,000 mph
The SR-71 cruised at Mach 3.2, more than 2,000 mph, around 85,000 feet.
What is the speed of sound at 10 C?
| Temperature – t – (oC) | Speed of Sound – c – (m/s) |
|---|---|
| 0 | 331.4 |
| 5 | 334.4 |
| 10 | 337.4 |
| 15 | 340.4 |
How do you calculate mach speed?
The Mach number (M) is simply the ratio of the vehicle’s velocity (V) divided by the speed of sound at that altitude (a). For example, an aircraft flying at Mach 0.8 is traveling at 80\% of the speed of sound while a missile cruising at Mach 3 is traveling at three times the speed of sound.
How can you measure the speed of sound?
SPEED=DISTANCE/TIME. To work out the speed of the sound in metres per second, divide the distance in metres by the average time in seconds. For example 170 metres divided by 0.50 seconds = 340 m/s.
Does sound travel at constant speed?
The speed of sound in the atmosphere is a constant that depends on the altitude, but an aircraft can move through the air at any desired speed.
How do you calculate the speed of sound?
SPEED=DISTANCE/TIME. To work out the speed of the sound in metres per second, divide the distance in metres by the average time in seconds. For example 170 metres divided by 0.50 seconds = 340 m/s. You have calculated the speed of sound!
What is the formula for speed of sound?
The speed of sound formula is given by. c = √γ×Pρ. = √1.4×2 / 0.034k. Therefore, speed of sound = 286.97 m/s. Example 2. Calculate the pressure if sound travels through a medium that has a density 0.05 kPa and speed of sound is 400 ms-1.
What is the speed of sound in kilometers per hour?
A speed of sound is equal to 1,234.8 kilometers per hour, so to convert simply multiply by 1,234.8.
How many mph is the speed of sound?
The speed of sound is 740 mph when the air temperature is 32 degrees. A general rule is that sound travels one mile in 5 seconds at sea level. Light travels at 186,000 miles per second, a speed so great that, for practical use, it can be considered to be instantaneous.
