Speed of sound in still 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.

# Air speed velocity of a swallow?

The fastest swallow is the white-throated needletail (hirundapus caudacutus), with a maximum recorded speed (according to the Guinness book of world records) of 172 km/h.

# What instrument measures air velocity?

Anemometers measure air velocity. The spinning cups of aweather station are a typical application. . Air velocity can also be measured using a pitot tube connectedto a gauge

# What is the velocity of sound in air?

The accepted value of speed of sound in air is determined by the equation. vT= (331.5 + 0.607T) m/s for the value T, put the temperature in. This will give you more accurate

# What is the Velocity of air at sea level?

The speed of sound in air has really nothing to do with the sea level and its atmospheric pressure. Speed of sound is dependent on the temperature. Look at the link: "Spee

# How does air resistance increase with velocity?

Air resistance is directly proportional to velocity. If you think about it, the faster an object is moving, the more frequently and harder said object will collide with the mo

# What is air velocity?

Speed of sound in air is c â 331 + 0.6 Ã T. T = Temperature. Speed of sound in air at 20Â°C is c â 331 + 0.6 Ã 20 = 343 m/s.

# How do you calculate for velocity of sound in air?

Speed of sound in air is c â 331 + 0.6 Ã T. T = Temperature. Speed of sound in air at 20Â°C is c â 331 + 0.6 Ã 20 = 343 m/s.

# What is air velocity of air flow in an air conditioning room?

Not sure I understand your question, Velocity is the speed in feet per minute the air is moving. This is usually associated with the duct system. In a room the velocity of the

# How do you measure the velocity of air?

It's called an anemometer and is best described as a sort of fan where the blades are pushed by the wind. Meteorologists have a standard for the particulars of such a fan so t

# What is the approximate velocity of sound in the air?

the velocity of sound in the air is 300m/s

# Why a raindrop falling vertically through still air reaches a constant velocity?

The air friction is proportional to surface area and square of velocity and so it increase square as velocity increase. At the rate when these friction force is balance with g

# What is air speed velocity of a sparrow?

African or European?

# Is higher velocity air colder?

No, it is the same temperature. When the wind is light/still, the heat from your body causes a warm pocket of air to form around you. When the winds have a higher strength, th

# What will affect the velocity of sound in air?

The speed of sound is dependent on the temperature. Speed of sound in air is c â 331 + 0.6 Ã T. T = Temperature. Speed of sound in air at 20Â°C is c â 33
