In SI units with dry air at 20 °C (68 °F), the speed of sound c = 343 m/s.
This also equates to 1235 km/h, 767 mph, or 1125 ft/s. Formula for the speed of sound in m/s is: c = 331 + 0,6 x °C That gives e.g. at the temperature of 20 °C a speed of sound: c = 331 + 0,6 x °C = 343 m/s.

∙ 9y agoS being the symbol for a unit of speed, a unit of measurement is about 761 mph in air and at sea level it is about 660 mph at jet altitudes. Which equals to approximately 340 to 295 m/s at aircraft in SI units.

∙ 10y agoYou pretty much have to measure it. You can't use an equation to
find the speed of sound, any more than the speed of a car.
Actually, there IS an equation. It's rough and approximate, because
it came AFTER the measurements, and it's an attempt to MASH the
measurements into the form of an equation:
In air, the speed of sound is ≈ 331 + 0.6 × T.
T = Celsius temperature
Don't expect exact, reliable results from this one.

∙ 12y agoEquation for the speed of sound in air is c ≈ 331 + 0.6 × T.
T = Temperature.
Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

Velocity of sound in acetone?
Velocity of sound in Acetone is about 1174 m/s
What is the approximate velocity of sound in the air?
the velocity of sound in the air is 300m/s
When was Velocity of Sound created?
Velocity of Sound was created on 2002-10-08.
What is the velocity equation?
If the velocity is constant then it is enough to use the equation, s = vt. S- the displacement, t - time elapsed and v the uniform or constant velocity. If velocity changes, then acceleration is there in action. Hence the final velocity after time t will be given as v = u + at.
Give the effect of density on velocity of sound?
as density of medium increase velocity of sound decreases.
What does vf mean in a science equation?
final velocity. it is used in multiple equations. its opposite would be vi, initial velocity. they mean exactly what they sound like. final velocity is the last velocity something was going at in the measured time, initial would be the very first velocity at a measured time.
What is the equation for fluid flow?
is the equation for flow velocity
What is the equation for acceleration?
Final Velocity- Initial Velocity Time
What is the velocity vector equation?
You have to solve Newton's equation ΣF=ma in order to find the velocity and displacement vectors.
