silencer inner tube diameter affect on noise
Discussion
What effect would the diameter of the inner perforated tube wrapped in (second part of the question..) glass fibre or steel wool, have on the exhaust? Specifically, volume.
I can come up with two theories;
A - a smaller tube has less surface area for muffling to work on, gases will flow faster and carry more energy And therefore noise.
B - a larger tube is less of a restriction, gas flows through at a lower pressure, less pulses are absorbed by the muffling, therefore more noise.
C - I'm a spanner.
Clearly only two of these can be correct. The pipe is 500mm long, and 2.25 OR 2.5 inches wide.
