Segment V8.5: Car Exhaust System

(Related to Textbook Section 8.4.2 - Minor Losses)

Pipe systems often contain multiple pipes in series or parallel in addition to system components other than straight pipes.

Although simple in concept, a rather complex pipe system is needed to carry engine exhaust from the unsteady outlet flow at the exhaust valve ports of the engine block to the nearly steady flow at the end of the exhaust pipe. In addition to numerous curves and corrugations in the pipes, the system contains a muffler with its complex flow geometry, an exhaust header (or manifold) with its parallel pipe configuration, and other components.
