Structural Analysis of the Exhaust Gas Silencer for the Flow through Perforated and Non-perforated Silencer

To minimize unwanted noise, the exhaust gas of high pressure and high temperature coming out of internal combustion engine passes through silencer. Various types of silencers like absorptive, reactive and resonating, perforated type are widely implemented in actual practice .perforated reactive mufflers have an effective damping capability. This paper deals with comparative structural analysis ...

Disposable infusion pumps.

PURPOSE The properties, performance, and applications of nonelectric disposable infusion pumps are reviewed. SUMMARY All nonelectric disposable infusion pumps exploit the same physical principle: mechanical restriction within the flow path determines the speed of pressurized fluid. The pressure generated by disposable pumps on fluid is 250-600 mm Hg, compared with 5-1200 mm Hg of pressure for...
