Sonic Velocity Calculator

Have you ever wondered how fast sound travels? The speed of sound, also called sonic velocity, depends on temperature, gas type, and molecular mass. Our Sonic Velocity Calculator makes it simple. You don’t need complex math or long formulas. Just enter the values, and you’ll get the result in seconds.

What is Sonic Velocity?

Sonic velocity is the speed at which sound waves move through a medium. In plain words, it’s how fast sound travels in air, water, or any gas. For example, sound moves faster in hot air than in cold air. That’s why voices sometimes carry farther on warm days.

How Do You Calculate Sonic Velocity?

The formula for sonic velocity looks like this:

Vs = √(γ × R × T / M)

Where:

• Vs is the sonic velocity in meters per second
• γ (gamma) is the adiabatic constant
• R is the universal gas constant
• T is the absolute temperature in Kelvin
• M is the molecular mass of the gas

Example: If γ = 4, R = 8.314, T = 200 K, and M = 50 kg/mol:

Vs = √(4 × 8.314 × 200 / 50)

Vs = 11.53 m/s

So, the sound would travel 11.53 meters every second in that medium.

How to Use the Sonic Velocity Calculator

Our tool is easy to use:

1. Enter the adiabatic constant (γ).
2. Enter the gas constant (R).
3. Add the temperature (C, F, or K).
4. Enter the molecular mass of the gas.
5. Choose your unit (m/s, ft/s, mph, km/h, or knots).
6. Click calculate.

The calculator will convert units, apply the formula, and show the result with step-by-step details. You’ll even see temperature and mass conversions if needed.

How far does sound travel in 17 seconds?

If the sonic velocity of air is about 343 m/s, then:

Distance = Speed × Time

= 343 × 17

= 5831 meters

So, sound can travel about 5.8 kilometers in 17 seconds.

What are the three formulas for velocity?

Velocity can be found with:

1. v = d / t (distance over time)
2. v = u + at (initial velocity plus acceleration × time)
3. v² = u² + 2as (relation between velocity, acceleration, and distance)

These formulas show how velocity works in motion physics.

What is the sonic velocity of air in ft/s?

At room temperature (20°C or 293 K), the sonic velocity of air is:

343 m/s × 3.28084 = 1125.3 ft/s

So, sound moves about 1125 feet per second in air.

Final Verdict

The Sonic Velocity Calculator is perfect for students, engineers, or anyone curious about sound. It saves time, avoids manual errors, and gives instant answers. Whether you’re learning physics or testing gas properties, this tool will help.

FAQs

Why does sound travel faster in warm air?

Because warmer air has more energy, which lets particles vibrate faster.

Can I use this calculator for liquids?

Yes, as long as you know the right constants for that liquid.

Is sonic velocity the same as Mach speed?

Not exactly. Mach number is a ratio of an object’s speed to the local speed of sound.
