Calculate Speed of Sound in fibrous material

c= speed of sound in air = 344 meters or 1128.6 feet c'= speed of sound in long fiber wool P= packing density of the fibrous material = 8kg/m3

Speed of sound in air [c]: m/s Packing density of the fibrous material [P]: kg/m3   Speed of sound in long fiber wool [c']: m/s
