At normal atmospheric pressure, the temperature dependence of the speed of a sound wave through dry air is approximated by the following equation: v = 331 m/s + (0.6 m/s/C)•T where T is the temperature of the air in degrees Celsius.
17 Ιουν 2023 · Find the speed of sound on a cold day when the temperature is 2 °C. The simplest formula for finding the answer is the approximation: v = 331 m/s + (0.6 m/s/C) • T
25 Ιουλ 2024 · The speed of sound increases as the air temperature increases. The precise formula is: c_air = 331.3 × √(1 + T/273.15), where T is the air temperature in °C. This formula returns speed in m/s.
Explain the relationship between wavelength and frequency of sound; Determine the speed of sound in different media; Derive the equation for the speed of sound in air; Determine the speed of sound in air for a given temperature
For the specific example of dry air at 20°C, the speed of sound in air is 343 m/s, while the rms speed of air molecules is 502 m/s using a mean mass of air molecules of 29 amu. Doing this calculation for air at 0°C gives v sound = 331.39 m/s and at 1°C gives v sound = 332.00 m/s.
