| As will be seen the percentage loss to the silencer appears independent of the power out- put, i.e. of the mass of gas flowing along the pipe, and we may therefore assume with reasonable certainty that this is a second- ary effect, and the point of primary import- ance in an exha- ust systems pow- er loss, is the wave effect of the gases pass- ing through the silencer. | ||
