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
Solved Examples. Q.1: The sound waves travel in the air with a density of 0.034 kg/m³ and pressure of 2k Pa with a temperature of 2°C. Calculate the speed of the sound. Solution: As given here: Temperature, T = 2° C. Density, \(\rho = 0.034 kg/m³ \) and, pressure P = 2k Pa. i.e. P = 2000 Pa. as we know that specific heat ratio in air is ...
Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. A disturbance introduced in some point of a substance - solid or fluid - will propagate through the substance as a wave with a finite velocity.
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.
The speed of sound is affected by temperature in a given medium. For air at sea level, the speed of sound is given by \[v_w = (331 \, m/s)\sqrt{\dfrac{T}{273 \, K}},\] where the temperature (denoted as \(T\)) is in units of kelvin. The speed of sound in gases is related to the average speed of particles in the gas, \(v_{rms}\), and that
