rotary intercambiador de calor ruido atenuación

Overview

Engineering reference data for Rotary Heat Exchanger Noise Attenuation in acoustics.

Key Formulas

Speed of Sound

$c = \sqrt{\gamma R T}$

Speed of sound in an ideal gas.

Sound Level

$L = 10 \log_{10}(I/I_0)$

Decibel level.

Wavelength

$\lambda = c / f$

Wavelength = speed / frequency.

Variables
