The speed of sound is affected by temperature in a given medium. For air at sea level, the speed of sound is given by \[v_w = (331 \, m/s)\sqrt{\dfrac{T}{273 \, K}},\]
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
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.
T = absolute temperature (o K, o R) For an ideal gas the speed of sound is proportional to the square root of the absolute temperature. Example - Speed of Sound in Air. The speed of sound in air at 0 o C (273.15 K) and absolute pressure 1 bar can be calculated as. c = (1.4 (286.9 J/K kg) (273.15 K)) 1/2 = 331.2 (m/s) where. k = 1.4 . and . R ...
