NettetThe shock wave of a coal and gas outburst is a high-pressure and high-speed impact airflow formed rapidly after the outburst. The propagation destroys the ventilation facilities and causes the destruction of the ventilation system. The theoretical research on the outburst shock wave is of great significance. In order to deeply understand the … Nettet47–5 The speed of sound. Our deduction of the wave equation for sound has given us a formula which connects the wave speed with the rate of change of pressure with the density at the normal pressure: c2s = (dP dρ)0. In evaluating this rate of change, it is essential to know how the temperature varies. moshi clear guard cover macbook

By definition, the energy transfer rate is given by the Power. Since we are considering a volume in space, it would be perfectly normal to find the Volumetric Power. Nettet11. mar. 2024 · A source tells me that the intensity of a wave is given by I = 2 π 2 f 2 A 2 ρ v, where f is the frequency of a wave, A is the amplitude, ρ is the density of the string and v is the velocity of the wave.
