Web2 apr. 2024 · As the silencer inner area, aka volume, goes down, pressure goes way up. Welds have heat affected zones that can create spots weaker than the steels max tensile load. Poor surface finishes give sharp microtroughs that give cracks a place to start. Baffles inside the suppressor reduce volume and increase pressure. WebThe drop in pressure will be quite small (in a low velocity ductwork system) – typically around 1 Pa per metre run of straight ductwork. In this particular circular steel ductwork system the value is 1.3Pa/m (and this may be checked by using figure 4.3 in Guide C). The length of that duct is 5m, and so the pressure drop is 5 x 1.3 = 6.50Pa.
