WebThe quantity ρc is the characteristic resistance of the material and has units of mks rayls (Pa·s/m). Characteristic resistance is the real part of the complex characteristic impedance, with characteristic reactance being the imaginary part. In the literature, when the characteristic reactance is zero, such as for Web繊度センドfineness. がある．. 合成繊維 や絹糸などの円形断面をもつ糸の太さを表す単位として，テックス，デニールが使用される．綿，羊毛，麻などの 天然繊維 の断面は円形でないものが多く，複雑な形状をしている．このような 繊維 の糸の太さを表す ...

WebJan 27, 2012 · – Pa*s/m2 is the same as Rayls (5000 Rayls is 5000 Pa*s/m2 , or 5 kPa*s/m2). I use the terms "air flow resistivity" and "kPa*s/m2" because this is the terminology used in the technical documentation I have read, which is attached to this post. The products are sorted according to their air flow resistivity value, lowest numbers first.

These have the same dimensions as momentum per volume. The units are named after John William Strutt, 3rd Baron Rayleigh. They are not … See more Specific acoustic impedance When sound waves pass through any physical substance the pressure of the waves causes the particles of the substance to move.
