If pressure .drop for the system is too high, use the next larger catalytic <br /> silencer and recalculate the pressure drop. <br /> Example: Flow Rate 1618 ACFM <br /> Exhaust Gas Temperature 10000F (14600R) <br /> Maximum Pressure Drop 10 in. W.C. <br /> 1618 ACFM = 44 lbs/min <br /> From Table II a 8MCS0 50 will be sufficient. K = 7.2. <br /> AP = K1A 12 To (2.096 X 10 8) = 7.2 (0.349s ) (1460) (2.096 X 108) <br /> AP = 3.5 In. W.C. <br /> C/25 <br />
